国土尺度河流干扰度评价与空间分布制图研究

摘要:
自然流淌河流(free-flowing rivers)提供多种生态系统服务,具有重要的自然价值与保护意义。中国处于快速发展的阶段,河流开发与保护的矛盾日益凸显,自然流淌河流尚未得到系统的保护。通过叠加不同的河流干扰数据集进行中国国土尺度的河流干扰度评价,绘制基于河流干扰指数(river disturbance index)的国土尺度空间识别地图来识别自然流淌河流的空间分布。根据结果分为5个级别:潜在的自然流淌河流、低干扰河流、中等干扰河流、强干扰河流、严重干扰河流,分别约占中国河流长度的6.85%、5.37%、24.39%、19.89%、43.5%。希望能为中国的河流保护、流域规划、保护地的生态系统保护评估与国土空间规划等提供参考。

Abstract:
Free-flowing rivers, which provide a variety of ecosystem services, have important natural values and protection significance. China is in a stage of rapid development, at which the contradiction between river resources development and protection is increasingly prominent. Free-flowing rivers have not yet been systematically protected. In this paper, we use a series of data sets indicating different levels of river disturbances to evaluate rivers at China’s national scale, and make a spatial map of river distributions based on a river disturbance index. We divide the river disturbances into five levels, including the potential free-flowing rivers, low impact disturbance rivers, medium impact disturbance rivers, high impact disturbance rivers and strong impact disturbance rivers. They account for 6.85%, 5.37%, 24.39%, 19.89% and 43.5% of the river length in China respectively. The research intends to provide reference for river protection, watershed planning, ecosystem assessment, comprehensive planning of protected areas and territory development plan in China.
