| Arable land is the most basic resource carrier for both the needs of human survival and the development of social economy.However,on the one hand,due to the rapid economic development before the land non-agricultural,non-food and other problems,the pressure to adhere to the red line of cultivated land protection is increasing day by day;On the other hand,in the process of promoting new urbanization,there is a lack of supervision and scientific guidance for the use of cultivated land,which leads to serious degradation of cultivated land quality,deterioration of cultivated land ecological environment and serious problems of cultivated land protection.The ecological environment of Gansu province is fragile,but it is the main grain producing area in western China.Therefore,the research on ecological compensation mechanism based on ecological compensation standard in Gansu Province is of great value to promote the improvement of cultivated land quality and the protection of ecological environment in Gansu Province.This paper tries to pass a both scientific and rationality of calculation model to detect the cultivated land ecological compensation standard of gansu province,this paper adopted in 2020 in gansu province are 12 district cities,two state population and five main crop data and social economic development,and land use of the ecological service value model,ecological integration model and compensation coefficient model,Finally,the cultivated land ecological compensation standard of each city in Gansu province is calculated through the integrated model of ecological compensation standard constructed.Then,based on the status quo and existing problems of cultivated land resources in Gansu Province,a cultivated land ecological compensation mechanism is constructed in accordance with the actual situation of Gansu Province.Through the comprehensive model of cultivated land ecological compensation standard in Gansu Province,the conclusions are as follows:(1)In 2020,the cultivated land ecological compensation standard of Gansu Province was 10.237 billion yuan,and the average ecological compensation standard of each prefecture-level city was 731 million yuan.The cultivated land ecological compensation standard of seven prefecture-level cities was above the average standard,among which Dingxi city was compensated up to 1.997 billion yuan.There was a significant regional gap in the cultivated land ecological compensation standard within the province.The standard of service compensation of several traditional agricultural cities in the province is high.(2)After measuring the ecological footprint and ecological carrying capacity,the ecological overload index of Gansu Province as a whole is positive and less than 1.The ecological resources in Gansu province are generally in surplus,and the cultivated land ecological resources can meet the consumption of people in the region.(3)The urbanization level of Gansu Province is between 0.36 and 0.94,with a large overall gap.The urbanization level of Hexi Region is relatively high,and the comprehensive Engel coefficient is between 0.281 and 0.395.All prefecture-level cities are lower than the international standard of 0.4,indicating that they are relatively rich on the whole.Finally,the compensation coefficient of Gansu province is between 0.569 and 0.597. |
