森林生态承载力评价综述
摘 要
森林资源是地球上重要的资源之一，它能够为人类提供生活必需品并且还具有涵养水源，保持水土，调节空气，增加降水，降低风速，防风固沙，改良固结土壤，净化空气，改善环境多种生态功能。随着可持续发展成为全球各国普遍接受的经济和社会发展模式，资源和环境承载力的研究已成为生态与环境领域的研究热点。基于当今生态问题和环境追究责任制的需要，将承载力与生态安全相结合，利用PSR模型，以熵权法确定指标权重，分析研究区森林生态承载力变化情况。在对森林生态承载力评价过程中不同环境要选择不同的评价方法，要因地制宜。

Evaluation of forest ecological carrying capacity
ABSTRACT
Forest resources are one of the most important resources on the earth. They can provide human life essentials and also have water sources, maintain water and soil, regulate air, increase precipitation, reduce wind speed, prevent wind and sand, improve soil consolidation, purify air and improve environment. Ecological function. As sustainable development has become a universally accepted economic and social development model in the world, research on resources and environmental carrying capacity has become a research hotspot in the field of ecology and environment. Based on the current ecological problems and the need of accountability system, the bearing capacity and ecological security are combined. The PSR model is used to determine the index weights by the entropy weight method, and the changes of forest ecological carrying capacity in the study area are analyzed. In the process of evaluating the ecological carrying capacity of forests, different evaluation methods should be chosen for different environments, and local conditions should be adapted.
Keywords: Forest resources;ecological carrying capacity; evaluation method
随着人类社会的发展，人口的增多生态环境遭到破坏，森林资源紧缺，对于森林承载力的调查研究迫在眉睫。
