ANALYSIS OF SPATIAL DIFFERENTIATION CHARACTERISTICS AND DRIVING FACTORS OF "NON-GRAIN" CULTIVATED LAND IN HENAN PROVINCE
As a major agricultural province,the phenomenon of "non-grain" cultivated land in Henan province becomes increasingly obvious.Clarifying the spatial differentiation characteristics and driving factors of "non-grain" cultivated land in Henan province can provide decision-making references for the prevention and treatment of "non-grain" cultivated land and the optimization of land use.This research adopted spatial autocorrelation analysis to study the spatial differentiation pattern of "non-grain" cultivated land in Henan province,and used the geodetector model to explore its driving factors.The results showed that:(1) The average rates of "non-grain" cultivated land in Henan province in 2010,2015,and 2020 were 32.12％,29.15％,and 32.21％,respectively,showing a certain range of fluctuation.The rate of "non-grain" cultivated land increased by 3.06％ from 2015 to 2020,currently being at a moderate level of "non-grain" cultivated land.(2) A spatial differentiation pattern had been formed in the southwestern (Nanyang city,Sanmenxia city) and central (Zhengzhou city,Kaifeng city,Xuchang city) regions of Henan province and low in the northern (Xinxiang city,Hebi city,Anyang city,Puyang city,Jiaozuo city) and eastern (Zhoukou city,Shangqiu city) regions,with evident clustering characteristics.(3) The spatial differentiation pattern of "non-grain" cultivated land in Henan province was the result of the combined effects of multiple factors,among which elevation,per capita consumption level,per capita arable land area,and slope had a strong impact on this pattern change.In summary,during the research period,the "non-grain" cultivated land in Henan province showed an upward trend and significant spatial differentiation characteristics under the drive of economic and natural resource conditions,among other factors.Based on the temporal and spatial evolution characteristics of the "non-grain" cultivated land in Henan province and the analysis of its driving factors,this provides a decision-making reference for the government to precisely formulate measures against the "non-grain" cultivated land.
