| 摘要: |
| 以关岭自治县沙营乡前进村为研究区，选取影响整理前后耕地质量的自然条件和农田基本建设情 况两大基本因素建立耕地质量评价体系，运用GIS平台的图层叠加法对耕地质量进行评价，生成耕地质量 评价图，将该区的耕地质量划分为4个等级。项目实施前，前进村土地质量没有一等地，二、三等地的总 面积为80.57hm 2 ，占总面积的86.14%，随着灌排工程、道路工程和土地平整工程的实施，项目区的土地 质量得到明显改善和提高。整理后，将土地质量等级分为一、二、三、四等，各级土地所占比例分别为 48.45%、18.62%、19.6%、13.34%。 |

| Abstract: |
| Taking Qianjin country， Shaying town， GuanLing autonomous county as the research area， this paper established an evaluation system of land quality based on the selected two basic factors， i.e.， the natural condition and the farmland construction situation that influenced the quality of cultivated land before and after the land con- solidation. It evaluated the land quality using the Diagram Cascading Addition of GIS platform and divided the qual- ity of the land into four grades according to the produced diagram of land quality Before the implementation of the project， the total area of second and third grade land（without first grade land） was 80.57hm 2 accounting for 86.14% of the total area. After the implementation of irrigation， road and land leveling project， the land quality of project area had been improved obviously which was divided into first， second， third and fourth grade， accounting for 48.45%， 18.62%， 19.6% and 13.34%， respectively. |
