Differentiation characteristics and influencing factors of cultivated land utilization intensity in Shaanxi Province
In this study,investment intensity and technical efficiency evaluation methods were employed to an-alyze the intensity of cultivated land development and utilization,as well as the driving factors,across different scales in Shaanxi Province,including provincial,regional,and municipal levels.The results showed that:(1)From the perspective of the intensity differentiation index P value of input factors per unit cultivated land area in Shaanxi Province,there was not much difference in labor and machinery input(P=0.409 and P=0.649,re-spectively)and they were relatively uniform at different scales.However,the input of biological chemistry exhibited significant differentiation characteristics,with P values of 0.847,1.026,and 1.472 for chemical fertilizer,pesti-cide,and agricultural film elements,respectively.(2)Based on the explanatory power(q value)of the influencing factors,the driving forces affecting the differentiation in cultivated land development intensity in Shaanxi Province were ranked as follows:urbanization rate(0.866)＞cultivated land quality(0.855)＞per capita disposable income of farmers(0.551)＞cultivated land topography(0.485)＞gross domestic product(0.210)＞cultivated land area per laborer(0.202).The influence of socio-economic conditions and natural basic conditions of cultivated land on the intensity of cultivated land utilization was higher than that of cultivated land management and utilization factors,and the socio-economic conditions were the dominant factors determining cultivated land utiliza-tion intensity.(3)The development intensity of cultivated land in 87.85％of counties in Shaanxi Province was ba-sically in the highest profit configuration,and biological chemistry input factors were the main limiting factors for cultivated land production efficiency in Shaanxi Province.
