Question 1: Reading the isotherm distribution map in July, the isotherm of Hainan Island is closed, and the value decreases from the periphery to the center, indicating that the distribution of Hainan Island in July is low in the middle and high in the periphery. The reason is that Hainan Island is high in the middle and low around.
Question 2: The annual temperature in Hainan Island is only about 10℃. The main reason for the low temperature in the whole year is that it is located at low latitude and is greatly influenced by the ocean.
Question 3: Yantian in Hainan Island is located on the west coast of the island, with flat terrain and numerous coastal beaches; Located on the leeward slope of the mountain, with little precipitation; Low latitude, high temperature and large evaporation.
Question 4: The climate of Hainan Island belongs to tropical monsoon climate, and the agricultural regional types are monsoon paddy field agriculture and tropical plantation agriculture.
Question 5:
(1) Read "Hainan Island Fruit and Vegetable Listing Schedule". Vegetables and watermelons are listed in winter in Hainan Island and in summer in the north. Hainan Island is located in the tropics, with sufficient light and heat and high temperature in winter, which is suitable for the production of vegetables and watermelons. The winter temperature in northern China is mostly below zero, so under natural conditions, vegetables and watermelons can only be harvested in summer.
(2) According to the above information, the economic development of Hainan Island should play the role of "big greenhouse" of Hainan Island, and make use of the seasonal differences between Hainan Island and northern provinces to build a series of winter melon and vegetable products and processing bases that meet the market demand and face the domestic and foreign markets, so as to promote the agricultural economic development of the whole region.
