珠江流域水土保持区划

Soil and Water Conservation Planning of Pearl River Drainage Area

珠江流域是一个复合流域,土壤侵蚀类型为水蚀。流域存在石漠化、崩岗等水土流失问题,呈明显的地带性分布特点。依据区域水土流失特点及经济社会对水土流失防治需求的分异规律,珠江流域划分为黔中山地、滇黔高原山地、黔桂山地、滇黔桂峰丛洼地、南岭山地、岭南山地丘陵、桂中低山丘陵、华南沿海丘陵台地8个分区。

Pearl River Drainage Area is a complex watershed, and its soil erosion type is water erosion. Pearl River Drainage Area has stony desertification and slope collapse problems, which is obvious zonal distribution. According to the characteristic of regional soil and water conservation, as well as differentiation law of economic and social demands for prevention and control of soil and water loss,Pearl River Drainage Area can be divided into the following 8 subareas: hill area of Middle Guizhou province plateau mountain area of Yunnan-Guizhou province hill area of Guizhou-Guangxi province peak clusters depression area of Yunnan-Guizhou-Guangxi province hill area of Nanling region mountain and hill area of Lingnan region low mountain area of Middle Guangxi province South China coastal hills platform area.
