资源环境承载力研究进展及其主要问题剖析

人们对资源环境承载力的研究由来已久。它是环境科学研究中衡量环境质量状况和环境容量受人类生产生活活动干扰能力的一个重要指标,资源环境承载力由承载体、承载对象、环境承载率三要素组成;衡量承载力的指标可分为自然资源支持力,环境生产支持力和社会经济技术支持水平三项指标。目前,各种类型的资源环境承载力的研究已形成了一个环境生产力集合,如区域环境承载力、资源环境综合承载力、资源环境要素承载力等。

The Present Situation of Resource Environmental Beating- Capacity Research and Analysis of its Main Problems

The scholars began their researches into resource environmental bearing-capacity for a long time. It is an important index used to monitor environmental quality and influence level of human activity on environment. Resource environmental bearing-capacity consist of three key elements--- bearing-substance, bearing-objective and environmental bearing-rate. Indexes used to measure bearing-capacity are divided into sustaining-capacity, environmental production sustaining-capacity and social-economic technical sustaining level. At present various kinds of environmental bearing-capacity researches have already came into an aggregate of environmental productive forces, such as regional environmental bearing-capacity, resource environmental comprehensive bearing-capacity, resource environmental key element bearing-capacity and etc.
