摘　　要：西江是连接我国西南与华南两地区的重要"黄金水道",在全国区域协调发展和面向东盟开放合作中具有重要战略地位。随着珠江-西江经济带发展成为国家战略,必然掀起经济项目的开发建设热潮,从而造成自然斑块的变动加快,西江流域自然生态系统作为生态环境的重要支撑,也正面临着严峻的考验。采用生态学数量化方法,基于各类土地自然斑块的海量数据,分析广西西江经济带各类自然生态系统的空间分布,以期为西江流域生态环境建设和保护决策提供科学的参考依据。Xijiang is an important"golden waterway"connecting southwest China and South China.It plays an important strategic role in the coordinated development of the whole China and the open cooperation towards ASEAN.With the development of the Pearl River-Xijiang economic belt becoming as a national strategy,the upsurge of development and construction of economic projects will inevitably set off,which will accelerate the change of natural patches.As an important support of ecological environment,the natural ecosystem of Xijiang River Basin is also facing a severe challenge.Adopting the ecological quantitative method and based on the massive data of various natural patches of land,this paper analyzes the spatial distribution of various natural ecosystems in Xijiang economic belt of Guangxi,in order to provide scientific reference basis for the decision-making of ecological environment construction and protection in Xijiang River Basin.
