摘要
针对正在兴起的集科学、政策、管理于一体进行综合分析的“生态区评价”理论与方 法，本项研究就生态区评价中的空间范围确定的方法进行了探讨，并就其对全球变化的响应 机制进行了讨论。提出把自然单元、社会单元和信息单元进行复合（集成）的概念化模型，并以 此论证了生态区重要性与安全性水平排序的系统分析法。
Aimed at the theory and methods for ecoregion assessment integrating science, policy and management we probed into how to make the dimension of a certain area for assessment and discussed ecoregion's response mechanism to global change. A frame combining physical, social and information units was put forward and used for ecological security assessment. Systematic analysis was used to compare essentiality and security of an ecoregion. Under support of remote sensing, GIS and GPS, the frame and methods for assessing ecological and environmental security were brought forward to simulate reconstruction project of land use pattern and intensity under ecological security, and further to adjust existing land use pattern based on physical, social and information units. The methods that integrated physical, social and information were feasible for confirming spatial area in ecoregion assessment. Two cases were put forward to verify how to intergate three kinds of unit in ecoregion assessment. Case 1: comprehensive regionalization of natural disaster in China based on the basic unit theory. Case 2: analysis of regional ecological security and its response to global change through intergrating physical and social units.
