Test analysis:

(1) Combined with the legend, it can be directly seen from the figure that the expressway is ring-shaped and distributed in a network, in which the expressway lines are dense in the north and sparse in the south-central part. The main natural reasons are island shape and topographic factors. The coast and the north are relatively flat, and the south-central part is mountainous with high altitude.

(2) The location of agricultural production includes natural location factors and socio-economic location factors. Natural conditions generally include climate, topography and water and soil resources. For example, Yacheng has sufficient light and heat, flat terrain, fertile soil and abundant water resources. Socio-economic conditions generally include labor, transportation, market and policies. For example, Yacheng has a large population and is close to roads, railways, airports and seaports. It has a vast market and has the advantage of policy support.

(3) Pay attention to the influence on the input area and output area respectively when solving problems. For the imported places, it mainly solves the problems of few varieties and insufficient supply of vegetables in winter in Beijing, which can meet the needs of citizens and improve the quality of life; For export areas, Hainan's resource advantages can be transformed into economic advantages, which can promote local economic development, increase farmers' income, increase employment opportunities and stimulate the development of related industries.

(4) The hazards of typhoons are mainly manifested in the damage to ships and houses, the damage to transportation and telecommunications facilities, the impact on transportation, the reduction or failure of agricultural production, and the resulting casualties. Self-protection measures are mainly to pay attention to the weather forecast, don't go out when the typhoon comes, pay attention to closing the doors and windows at home, and stay in a safe place after a short calm in the typhoon eye.

(5) The connotation of sustainable development includes economic sustainable development, ecological sustainable development and social sustainable development, in which economic sustainable development is the foundation, ecological sustainable development is the condition and social sustainable development is the goal. From the perspective of sustainable economic development, we can actively develop various marine resources, improve economic benefits and improve the comprehensive utilization rate of marine resources. From the perspective of ecological sustainable development, it is necessary to develop moderately, prevent ecological damage and environmental pollution, establish marine nature reserves, and implement a fishing moratorium system. From the perspective of social sustainable development, it is mainly to increase employment opportunities and improve people's income and living standards.
