| 中文摘要: |
| 从土壤肥力、立地条件、基础设施和经济产出4 个角度综合选取12 个指标，用熵值法确定指
标权重并运用ArcGIS 软件进行空间插值与统计，分析珠海市1982-2009 年耕地质量时空变化规律。结果表
明，珠海市耕地质量1982 年以一级耕地为主，2009 年以二级耕地为主，1982 年一级耕地转为2009 年二级
耕地的面积为18 005.37 hm2，占2009 年二级耕地的60.73%，白蕉、乾务和平沙有大量的一级耕地转为二级
耕地。1982 年珠海市一级和二级耕地面积的比例分别为65.96% 和30.43%，而2009 年珠海市一级和二级
耕地面积的比例分别为8.25% 和80.85%，耕地质量有大幅变化。1982-2009 年期间，珠海市土地利用结构
发生重大变化，耕地总面积大幅度减少，耕地质量等级大幅下降，优质耕地主要分布在斗门区，其次是金湾
区，香洲区很少。 |

| This paper selected 12 indicators to establish the evaluation index system from four aspects of soil
fertility，soil conditions，infrastructure and economic output，determined the index weight by entropy evaluation
method，did the spatial interpolation and statistics using ArcGIS software，and analyzed the spatio-temporal
evolution of cultivated land quality of Zhuhai from 1982 to 2009. The results showed that the cultivated land of Zhuhai
concentrated in the first class in 1982 and the second class in 2009，the area of the first class of cultivated land
changing to the second class of cultivated land was 18 005.37 hm2 from 1982 to 2009，which accounted for 60.73% of
the total area of the second class of cultivated land in 2009，and in Baijiao，Qianwu and Pingsha town，there were a
lot of first class of cultivated land changing to the second class of cultivated land. In 1982，the proportions of the first
class and the second class of cultivated land were 65.96% and 30.43%. But in 2009，the proportions were 8.25% and
80.85%，the quality of cultivated land changed drastically. From 1982 to 2009，the structure of land use in Zhuhai
changed greatly，the total area reduced substantially and the level of cultivated land quality dropped quickly. The
quality cultivated land was mainly located in Doumen district，and less in Jinwan district and the least in Xiangzhou
district. |
