基于ArcGIS软件的广西耕地连片分析及应用——广西耕地红线研究系列论文之三

The Analysis and Application of Guangxi's Concentrated Arable Land Based on ArcGIS:On Boundary Line of Guangxi's Arable Land(Research Paper Ⅲ)

耕地分布集中程度直接影响着耕地的规模化利用和农业机械的运用。耕地连片性是考量耕地分布集中程度的重要指标。基于前人的研究,将集中连片耕地定义为在同一范围内具有一定空间相对相连程度且具备一定面积规模的耕地地块区或地块群,通过ArcGIS测算广西共有连片耕地376.80万公顷,占广西耕地总量的比重为85.26%,并根据该结果进行应用研究。

Scale utilization of arable land and application of agricultural machinery affect directly the degree of arable land concentration. The continuity of arable land is an important indicator in considering the arable land’s distribution of concentrative degree. Based on the research of predecessors, concentrated continuous arable land, defined as the arable land areas or clusters with a certain size has certain special relative degree of connection in the same scope. Through the measurement of ArcGIS, there is 3.768 million hectares of continuous arable land in Guangxi which accounts for 85.26% of the total arable land in Guangxi. And the applied research will be preceded on the basis of this measuring result.
