【摘要】 通过对研究区进行耕地地力评价,并将评价成果应用于基本农田调整,借助于GIS空间分析技术,得出研究区耕地质量优良的二、三级地的基本农田比重过小,而耕地质量低劣的四、五级地的基本农田比重过大。因此,结合研究区的实际情况进行了各级地基本农田分布调整,将二级地中基本农田的比重由36.26%调升为75.05%;将三级地中基本农田的比重由78.99%调升为84.96%;将四级地中基本农田的比重调低3.7%;将五级地中基本农田的比重由82.68%调低为65.36%。更多还原

【Abstract】 Through the cultivated land productivity evaluation and using GIS spatial analysis technique,taked the achievement applied in basic farmland adjustment.That study area of cultivated land quality secondary and tertiary of basic farmland proportion was too small,and cultivated land of the inferior quality of fourth and fifth levels of basic farmland excessive proportion.Therefore combining research area in its various basic farmland distribution adjustment.Adjust second levels of basic farmland by the proportion of 36.26% to 75.05%.Adjust third levels of basic farmland by the proportion of 78.99% to 84.96%.Adjust fourth levels of basic farmland by the proportion down 3.7%.Adjust fifth levels of basic farmland by the proportion of 82.68% to 65.36%.更多还原
