【摘要】：本文通过基尼系数、空间数据探索分析(ESDA)等统计方法,探索我国耕地后备资源各地类空间集聚特征及影响因素,为耕地后备资源的开发利用奠定理论基础.结果显示:(1)我国耕地后备资源各地类集聚程度差异较大,呈现出可开垦沿海滩涂可开垦沼泽地可开垦沙地、可复垦采矿用地可开垦内陆滩涂、可开垦盐碱地可开垦裸地可开垦其他草地的特征.(2)可开垦沿海滩涂主要聚集在东部中纬度沿海地区,可开垦沼泽地和可复垦采矿用地主要集中在东部偏北部地区,可开垦沙地为西北地区.(3)自然因素奠定了各地类空间分布的基本格局,人口因素对各地类集聚效应具有重要影响,经济因素属于辅助因素,但对耕地后备资源可持续开发利用的影响效力正在突显.通过实证分析,得出研究结论:基尼系数和ESDA中的趋势分析等方法从地统计的视角揭示并量化了耕地后备资源结构的空间分布特征,可为解译耕地后备资源的集聚效应、制定开发利用对策提供科学依据.
[Abstract]:This paper through the Gene coefficient, exploratory spatial data analysis (ESDA) and other statistical methods, the exploration of China's arable land reserve resources of all types of spatial agglomeration characteristics and influencing factors, lay the theoretical foundation for the development and utilization of cultivated land resources. The results showed that: (1) China's arable land reserve resources of all types of agglomeration differences, showing can be reclaimed coastal marshes can be reclaimed sand can be reclaimed, the mining land reclamation can be reclaimed inland beaches, features can be reclaimed saline can be reclaimed land can be reclaimed grassland. The other (2) can be reclaimed coastal land mainly gathered in the eastern coastal areas in middle latitude, can be reclaimed and reclamation of mining land mainly concentrated in the eastern part of the north in the swamp, sand can be reclaimed in the northwest area of China. (3) the natural factors laid a basic pattern around the class of space distribution, population factor has important influence on the agglomeration effect, economic factors Belongs to the auxiliary factors, but the impact of sustainable development and utilization of cultivated land resources are highlighted. The effectiveness through empirical analysis, draw the conclusion: trend analysis method and Gini coefficient in ESDA from a statistical perspective to reveal and quantify the distribution characteristics of arable land reserve resources structure space for interpretation of the agglomeration effect of arable land reserve resources and provide scientific basis for making countermeasures of development and utilization.
