由于自然条件和社会经济发展水平差异较大，中国不同地区面临的生态环境问题差异很大。这种空间变异性要求区域化的环境管理和保护政策。环境功能区划是设计和实施差异化环境政策的有效工具。为遏制中国不同区域的生态退化，我们首次构建了包括自然生态安全保护、人类健康生存环境维护和区域环境承载力三大要素的25项社会经济和环境指标的综合环境功能评价指标体系。为明确新时期中国环境功能区划，利用GIS和遥感技术进行环境功能区划。我们为25个指标生成了1 km分辨率的网格数据，并实施了该指标体系，以评估中国2414个县的环境功能。为不同区域设计并实施差异化的环境管理目标和策略，避免一刀切的现象。这项工作为差异化管理的设计和实施奠定了科学基础，提供了量化工具。通过不仅考虑自然系统，而且考虑社会和经济系统及其相互作用，这种环境功能评价提供了更全面的观点，从而为平衡环境保护和社会经济发展提供了新的见解。
Different regions in China face greatly dissimilar ecological and environmental problems due to large variations in natural conditions and socioeconomic development levels. Such spatial variability calls for regionalized environmental management and protection policies. Environmental function zoning is an effective tool for the design and implementation of differentiated environmental policies. To contain the ecological degradation in different regions of China, we first created a comprehensive environmental function evaluation index system that included 25 socioeconomic and environmental indicators for the three key elements of natural ecological security protection, healthy human living environment maintenance, and regional environment carrying capacity. To clarify the division of Chinese environmental function zoning in the new period, we use GIS and remote sensing technology. We generated 1-km resolution grid data for the 25 indicators and implemented this index system to evaluate the environmental function of the 2414 counties in China. Differentiated environmental management objectives and strategies were designed and implemented for different zones to avoid the phenomenon of one size fits all. This work lays a scientific foundation and provides a quantitative tool for the design and implementation of differentiated management. By considering not only the natural system but also the social and economic systems and their interactions, this evaluation of environmental function provides a more comprehensive view and thus offers new insights on balancing environmental protection and socioeconomic development.
