摘要/Abstract

摘要： 在人类的发展历史长河中耕地一直有着十分重要的地位。在保护耕地方面人类必须要做的事情很多,处理好耕地的供需矛盾是粮食安全的关键。随着南华县经济不断发展和人口的增长,影响耕地变化的原因越来越多。本次研究以南华县为研究区,基于遥感影像和GIS软件分析近五年该地区耕地的空间变化趋势,并运用SPSS软件分析影响南华县耕地变化的驱动因子。通过研究得出如下结论：自2015年以来,南华县耕地面积一直处于增加的过程,由平缓增加变为急速增加;南华县耕地的空间分布格局比较明显,增加的耕地主要位于南华县内水土资源良好的大部分地区,耕地减少的区域主要分布在原有耕地的边缘以及相邻地区,南华县耕地总体来说处于增加趋势;农民人均收入、农业生产总值、社会固定资产投资总额、粮食产量是影响耕地面积变化的主要驱动力。

Abstract: In the long history of human development, cultivated land has always played a very important role. In the protection of cultivated land, there are many things that human beings must do. To deal with the contradiction between supply and demand of cultivated land is the key to food security, and it is also a difficult problem to be solved by human beings.With the continuous economic development and population growth of Nanhua County, there are more and more underlying reasons for the change of cultivated land. Based on remote sensing images and GIS software, the spatial change trend of cultivated land in Nanhua County in recent five years was analyzed, and the driving factors of cultivated land change in Nanhua County were analyzed by SPSS software. According to the analysis, since 2015, the cultivated land area of Nanhua County has been in the process of increasing, from gentle increase to rapid increase. The spatial distribution pattern of cultivated land in Nanhua County is relatively obvious. The increased cultivated land is mainly located in most areas with good water supply and soil resources in Nanhua County, while the area of cultivated land reduction is mainly distributed in the edge of the original cultivated land and adjacent areas. Generally speaking, the cultivated land in Nanhua county is on the increase trend. According to the principal component analysis, per capita income of farmers, gross agricultural product, total social fixed asset investment, and food production are the main drivers affecting the change of arable land area.
