Land-Use and Land-Cover Change Simulation and Its Driving Forces in Fuyuan, Sanjiang Plain, 2000-2020

Abstract

As one of the most intact areas in the downstream of the Sanjiang Plain, Fuyuan is a key development area relying on the policy of "one island and two countries". Since 2000, the land use structure of Fuyuan has changed significantly due to natural and human factors. In this paper, We useed MARKOV to simulate LUCC ( Land-Use and Land-Cover Change) in Fuyuan from 2000 to 2020, calculating land use dynamic index , doing some correspondence analysis, and exploring its driving force factors. The results show that some land types are changed more violently. We analyzed the difficulty degree of land type mutual transformation, and the result is that the conversion of residential and other construction land is high, and the ecological reversibility is poor. Forest swamps and woodlands are most easily converted into cultivated land, and the competition is strong. Wetland is easy to convert into transport land; Fallow is the easiest way to estore wetlands. On this basis, we analyzed the natural factors and policy changes in the past 20 years, and concluded that human factors are the main driving forces for LUCC( Land-Use and Land-Cover Change),such as the urbanization process in Fuyuan and the implementation of policies about ecologically desertification and development of foreign trade, etc.
