1Research background
In December 2007, the “two-oriented society” (resource-saving and environment-friendly) comprehensive supporting reform pilot zone of the Changsha-Zhuzhou-Tan urban agglomeration was approved by the state. Faced with this once-in-a-lifetime development opportunity, the reform and development of the Changsha-Zhuzhou-Tan urban agglomeration has been elevated to a higher strategic level. The construction of the Changsha Greater Hexi Pilot Area with a high starting point and high standards is an urgent need to implement the national overall regional development strategy and explore the comprehensive supporting reform of the "two-oriented society"; it is a reality to expand the radiation function of the Changsha-Zhuzhou-Tan City agglomeration and promote the rapid rise of the central region Choice; is an important way to further deepen reforms and explore endogenous economic development models.
The Hexi Pilot Zone needs to adapt to the world's trend of regional economic integration, stay within the framework of the overall strategic development of my country's central and western regions and the province, explore its own scientific spatial layout, and promote rapid economic growth and sustainable development. , is the research direction that this article focuses on.
2 Research significance
2.1 Integrating planning ideas into coordinated regional development
In the context of economic globalization, trade liberalization, regional economic integration and the rise of central China, Against this background, Changsha City, located at the junction of China's East China Economic Circle and South China Economic Circle, and at the intersection of the Beijing-Guangzhou and Yangtze River industrial belts, has become one of the core cities in the central and western regions. The special geographical location has pushed Changsha to the most important frontier position of interconnection, radiation and integration between the "9 2" Pan-Pearl River Delta Economic Circle and Central China, Yangtze River Delta and Western Economic Circles. The GDP of Changsha, the core city of the Changsha-Zhuzhou-Xiangtan urban agglomeration, exceeded 200 billion yuan in 2007, ranking eighth in the comprehensive economic strength ranking of provincial capital cities across the country and first among cities in central China.
From a national level, the construction of the Hexi Pilot Area will help enhance the radiation effect of the Changsha-Zhuzhou-Tanzhou urban agglomeration, promote the rapid rise of the central region, and form a new pattern of regional coordination with complementary advantages and synchronous development; From the perspective of economic development in Hunan Province, the Hexi Pilot Zone is located at the junction of the three cities of Changsha, Zhuzhou and Tan, which can connect, flow and share the resources of the three cities, promote the construction of the Changzhutan urban agglomeration, and have a strong first-mover effect and The convergence effect radiates to the five cities of Yiyang, Changde, Loudi, Yueyang and Hengyang, driving the "3 5" urban agglomeration in Hunan and the overall economic and social development of the province.
2.2 Build an integrated urban and rural development coordination system
Currently, coordinating urban and rural development has become one of the ways to build a harmonious society. Our country is promoting the reform of the rural management system and promoting the construction of a new socialist countryside from top to bottom. The coordinated development of urban functional groups and efficient agricultural industrial zones is a very good opportunity for the Hexi Pilot District.
Accelerate the breaking of the dual urban-rural structure, explore new mechanisms to break the population constraints, resource constraints, and environmental constraints in the process of urbanization, and promote the concentration of land for large-scale operations, the concentration of farmers' residences in cities and towns, and the concentration of industry in parks concentrated. Establish a long-term mechanism to promote agriculture through industry and promote urban and rural development, extend urban municipal public facilities, modern information infrastructure, comprehensive management facilities and public service facilities to rural areas, and take the lead in forming a new integration of urban and rural economic and social development. pattern. Build the Hexi Pilot District into a resource-saving urban area that saves energy, land and materials.
2.3 Establish a sustainable ecological environment system
The superior ecological environment is a favorable condition for the sustainable development of Hexi Pilot District. Through the implementation of the coordinated development strategy of economy and environment, we will promote the "green "Threshold" system and the construction of "circular economy" demonstration bases to form a circular economy industrial chain. Explore the development model of circular economy in key industries and areas. Continuously improve the environmental capacity and economic benefits of resource utilization in the Hexi Pilot District, enhance the green competitiveness of the Hexi Pilot District, enhance the economic development potential, and build the Hexi Pilot District into an environmentally friendly urban area with a developed economy and a good ecological environment.

The higher-altitude mountains are used to plan ecological parks; tracts of basic farmland are used to plan high-efficiency agriculture and sightseeing agricultural areas, forming an ecological pattern in which natural ecological elements are wedged and extended from the Xiangjiang River to the hinterland of the planning area.
5 Several issues that should be paid attention to in planning
5.1 Coordinated urban and rural development
The Dahexi Pilot Zone is a pilot area for industrial transformation and new urbanization in my country. Therefore, we must pay attention to the orderly connection between the central city and the countryside, rely on the radiation and driving function of the central city, promote the transformation of industries from exogenous to endogenous, and achieve integrated urban and rural development.
In terms of land use layout, a four-level system of central cities, industrial groups, centralized towns and new rural residential areas will be constructed; in terms of infrastructure construction, the focus will be on water, electricity, roads, environment and other public facilities and residential areas. In terms of supporting facilities, it radiates from the central city to new rural residential areas step by step; in terms of industrial layout, a circular economic system with linkage of primary, secondary and tertiary industries is built to promote the mutual integration and coordination between efficient agricultural production areas and industrial groups at all levels. . Increase investment in agricultural science and technology, improve agricultural labor productivity, promote the transformation of traditional agriculture into modern agriculture, and provide more labor and agricultural and sideline products for the development of the tertiary industry in urban areas.
5.2 Protection and Utilization of the Natural Ecological Environment
The Hexi Pilot Area is crisscrossed by mountains, criss-crossed by rivers, and has complex and diverse landform types, including hills, hills, rivers, streams, and reservoirs. The altitude of the mountain peak is between 260~350m.
The ecological lands planned and protected mainly include Wushan Forest Park, Yuelu Mountain System (including Yuelu Mountain Scenic Area, Elephant Biwo Forest Park, and Meixi Lake Scenic Area), Wufeng Mountain Forest Park, and Quanshuichong Forest Park. , Gushan Forest Park, Jijiashan Forest Park, Yanghuyuan Ecological Wetland and other large-area green spaces, and strengthen the environmental management of Xiangjiang River, Jinjiang River, Baqu River, Longwang Port and other water systems. In addition, the basic farmland on the edge of the pilot area is about 100km2, which should be retained in the planning in conjunction with the efficient agricultural industrial layout.
5.3 Rapid Transportation Optimization
In rapid transportation optimization, consideration should be given to linking the West Ring Line (Changsha Fourth Ring Line) of the three cities of Changsha, Zhuzhou and Tan according to the mountain situation to promote inter-regional connections; strengthen cross-river transportation Channels, in addition to optimizing the traffic on the existing bridges on the Xiangjiang River, it is recommended to open the cross-river channel of Laodong West Road and Yingpan West Road to strengthen the connection between the two sides of the Xiangjiang River; plan the Tanwang Railway as the Changsha-Zhuzhou-Tanzhou intercity commuter railway; Feldspar The railway will be upgraded and expanded to strengthen railway transportation from Changsha to northwestern Hunan and connect with the main railway trunk lines in central and western my country.
5.4 Coordination with the overall spatial layout of Changsha City
The area and population of the east and west banks of Changsha City are basically the same, but the current urbanization and economic and social development levels are obviously unbalanced. Strong in the west and weak in the west, Hexi has become a "short leg" of Changsha. If Changsha wants to rise, Hexi must rise. In recent years, Liuyang City and Ningxiang County have actively moved closer to urban areas. The construction of Liuyang City Pharmaceutical Industrial Park and Ningxiang National Industrial Park are distributed along the Changchang and Changliu Expressways, and the development of the east-west axis has become more and more obvious. The construction of the Hexi Pilot Zone will create a new city between Changsha City and Ningxiang County, promote the rapid construction of the Jinzhou Industrial Belt, lead the development of Changsha to the west and deepen the hinterland, and incorporate Ningxiang County into the urban area of ??Changsha City. The future urban spatial structure of Changsha City will form a new pattern of balanced development of "east and west wings".
6 Conclusion
The development of Hexi Pilot Area is not only related to the economic development of the area, but also related to the success or failure of Changsha City's "two-oriented society" construction, and it is also related to Changsha, Zhuzhou and Tan cities. It is the key to the economic rise of the group and even Hunan Province. Properly formulating the spatial layout plan of the Hexi Pilot Area is a prerequisite for the healthy development of the city. This work is worthy of continued research and continuous improvement.
