摘要
鉴于农业生态系统与环境、社会、经济、人类等的复杂关系,该研究从区域角度出发,分别构建农业生态环境与农业生态经济评价指标体系及评价模型,并通过农业生态环境—经济发展协调度将二者整合,评判农业生态系统可持续发展的状况。研究中对生态环境质量及协调度评价结果划分等级,与GIS结合,制作成专题地图,并以江苏省为例进行了实证分析应用。结果表明: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,生态经济发展水平在1996—1999年间呈波动上升后逐年下降,但仍保持良好或优质协调状态。
Agro-ecosystem is closely related with environment, society, economy and human. To assess the agro-ecosystem environmental quality and ecological economy at the regional dimension, assessment index systems and models were established respectively. They were integrated by ecological environment-economic harmonious degree to quantitatively describe the status of the agro-eeosystem sustainable development. Environmental quality and harmonious degree were classed, and the thematic map was painted cooperating with GIS. Taken Jiangsu Province as a case, this study showed that the indexes of regional agriculture ecological environmental quality in Yan-Jiang, Yah-Hal and Liang-Huai regions was higher than the three others during 1996-2005, and environmental quality in most regions was improved. Ecological economy development level, during 1996-1999, expressed a wavelike rising tendency and subsequently decreased year by year, but the harmony was keeping good or perfect.
