Exploring the relationship between cultivated land change and economic development has become a hot issue for scholars.in this paper,The methods of regression analysis, land use elastic coefficient method, location entropy are used to empirically describe the relationship between cultivated land change and economic development.The results show: Since the 20th century, the change of cultivated land area has experienced three distinct stages of change, showing a process of recovery, decline, and steady evolution in Henan Province. The per capita cultivated land area is characterized by an upward trend, and the per capita cultivated land area is increasing year by year. In general, the intensive use of cultivated land in Henan Province is still not high, but the momentum of a sharp decline in cultivated land is basically controlled. The change of cultivated land area and economic development showed a four-time curve fitting relationship, which indicates that the path dependence of economic development on cultivated land occupation still exists, and cultivated land supports the rapid development of economy.The research results of the relationship between cultivated land change and economic development by using location entropy show that the spatial layout of the urban area is less than 0, and the regularity is not strong.The location where the location entropy is between 0-1 is mainly located in the central part of Henan Province;The cities with location entropy greater than 1 are mainly located in the eastern part of Henan. 1 The introduction cultivated land resources reducing is one of the major Cultivated land resource is human survival and cause of economic development, showing the trend of economic development of the basic factors of arable land decrease with economic production.But with the rapid development of development.Some scholars think that the cultivated urbanization and industrialization, the problem of land change and the economic development of a linear cultivated land loss caused extensive concern of the negative correlation between [4], some scholars of government and academic circle [1].Foreign scholars parts, according to a study by a rapid decline in of regional land use and interactive relationship of cultivated land with the increase of the per capita GDP, economic and social development have a profound characterized by exponential decline trend [5].Also the understanding of, and cobb Douglas production scholar thinks, between cultivated land and economic function model is adopted at quantitatively analyzes development showed a similar to the environmental the factors such as land, capital and labor contribution kuznets inverted "U" type curve characteristics, such to economic growth.Chinese scholars on the as Mr Fukuda of tianjin, shandong [6], gui-shan Yang relationship between the cultivated land change and of the Yangtze river delta economic developed regions economic development also made the positive such as arable land loss and economic development exploration, and achieved some research results relationship of quantitative analysis, verify the [2-3].At present, scholars generally agree that the existence of similar kuznets curve [7].How to This contribution has been peer-reviewed. https://doi.org/10.5194/isprs-archives-XLII-3-W10-1013-2020 | © Authors 2020.

Henan Province has 18 cities f(x) is a function of a firm, called the regression and 108 counties (cities).

During the the win-win goal of cultivated land protection and same period, the province achieved a GNP of economic development. 3707.2 billion yuan, the proportion of primary, 4.The results and analysis secondary and tertiary industries was 4.1 Analysis of cultivated land change 11.91:50.99:37.10, and the per capita GDP was From 2001 to 2014, the cultivated land 37072 yuan, which was 79.50% of the national per resources in Henan Province changed from 6907.3 capita GDP in the same period. The grain output is *103 hm2 in 2001 to 8124.66 *103 hm2 in 2014, and 57.723 million tons, accounting for 9.51% of the the number of cultivated land increased by 1217.36 national grain output. It not only feeds more than *103 hm2 in 13 years. During this period, the 1/13 of the population in China, but also exports 15 largest area of cultivated land was in 2009, billion kg of raw grain and manufactured products reaching 8192.01 * 103 hm2, and the smallest was every year, making a positive contribution to food 6907.3 * 103 hm2 in 2001.
