土地利用三大类变化分析是有关部门宏观掌握调查区域土地利用现状资源最为重要的关键数据,对地方耕地保护、资源利用及国土空间规划起到重要的数据支撑作用。本文以浙江某县为例,结合当地土地利用现状展开研究,分析三调成果三大类的流量变化趋势、增减空间分布以及引起三大类变化的原因等,从而为地方有效实施土地资源管控措施及合理开发利用土地资源提供技术依据。

The analysis of three kinds of land-use changes is the most important key data for the relevant departments to master the current situation of land-use resources in the survey area,which plays an important role in supporting the local cultivated land protection,resource utilization and land spatial planning.Taking a county in Zhejiang Province as an example,combining with the current situation of local land use,this paper analyzes the trend of flow change,the spatial distribution of increase and decrease,and the causes of the three kinds of changes,so as to provide technical basis for the effective implementation of land resource management and control measures and the rational development and utilization of land resources.
