中国生态环境敏感性及其区域差异规律研究

China's eco-environmental sensitivity and its spatial heterogeneity

我国日益恶化的生态环境越来越引起社会各界的关注。如何对生态环境问题采取有效的综合整治策略,已经成为科学界面临的一个挑战。本研究首先综述了我国主要生态环境问题——水土流失、沙漠化、盐渍化和酸雨的空间分布格局和空间相关性,提出了生态敏感性的概念,分析了影响我国主要生态环境问题敏感性的因素,特别是气候对生态环境敏感性的影响,综合地提出了中国生态环境敏感性分区,并探讨了各分区的特点。

The eco environmental degradation has been attracted more and more attention in China. It is becoming a challenge for scientists to find effective measures to tackle the eco environmental problems. In this study, we reviewed the spatial pattern and correlationship of major eco environmental problems: soil erosion, desertification, salinization, and acid rain. The concept of eco environment sensitivity was proposed, and the factors which influence the eco environment sensitivity in China were analyzed, especially climatic factors were focused. A regional classification of eco environment sensitivity in China was developed, and the characteristics of each sub region of eco environment sensitivity was described.
