【摘要】 本文以莱芜市里辛土地整理项目为例,采用GIS技术、实地调查和室内分析相结合,探讨了基于土地整理的耕地质量评价指标体系、评价方法及整理前后质量变化。结果表明,研究区在土地整理前后,耕地质量级别空间分布、面积和总体质量水平都发生很大改变。整理前耕地质量级别主要为二、三和四级地,占总耕地面积的89.32%,一级地很少;整理后基本为一、二级地,占总耕地面积的95.54%,三、四级地很少。整理后的耕地质量总体水平是整理前的1.3026倍。该研究方法对土地整理耕地质量评价有借鉴意义,评价结果可为莱芜市里辛土地整理绩效评价提供科学依据。更多还原

【Abstract】 Taking Lixin land consolidation(LC) project of Laiwu City as an example, integrating GIS technology, method of field survey and method of in office analysis, indexes system, method of arable land quality and its change based on LC were studied. The result indicated that grade spacial distribution, area and total level of arable land quality changed much before and after LC. Grades of arable land quality were mainly 2, 3 and 4 before LC, which occupied 89.32% of total arable land area, and grade 1 is little. Grades of arable land quality were basically 1 and 2 after LC, which occupied 95.54% of total arable land area. Total arable land quality level after LC is 1.3026 times before LC. The study method has instruction significance for arable land quality of LC, and valuation result can provide scientific basis for performance evaluation of Lixin LC project.更多还原
