摘　　要：鉴于农业生态环境与社会、经济、人类等的复杂关系,通过构建农业生态环境质量评价指标体系及评价模型,以江苏省为研究案例对江苏省六大经济区进行农业生态环境质量评价。结果表明:代表年份1996年和2000年江苏省平均植被覆盖度由54.74%下降到50.42%,轻度级以上的水土流失总面积比例由8.12%下降到6.76%;1996～2005年,江苏省沿江、沿海和两淮经济区农业生态环境质量发展水平高于徐连、宁镇扬和太湖经济区,大部分经济区生态环境质量等级均有提高。The eco-environment is closely related with society, economy and human. To understand the relation, an index systems and relative models for assessing the agriculture eco-environmental quality at the regional dimension were established. An application example in Jiangsu province was provided, it showed that the vegetation cover was reduced from 54. 74% to 50. 42%, the proportion of light water and soil loss area was decreased from 8.12% to 6. 76% in representative years 1996 and 2000. The index of regional agriculture ecological environmental quality in Yanjiang, Yanhai and Lianghuai regions was higher than the three others during 1996-2005, but environmental quality in most regions was improved.
