鄂西北丘陵山地水源区水源涵养和水质净化能力提升技术研究与示范技术指南

本技术指南结合湖北省丹江口水库周边小流域及森林实际情况编制，结合小 流域内子流域的划分，进行水质采样，通过相关性分析，冗余分析等方法确定了 影响小流域水质的主要地类因素及景观因素，研发了基于小流域土地利用类型及 景观格局指数对流域水质进行预测的方法，在滨水区域构建了植被缓冲带，研制 了适用于滨水植被缓冲带建设的坡度及宽度，在对凋落物及土壤层持水能力的基 础上研制了适用于水源涵养类型的林分建设指导。

This technical guide was compiled based on the actual conditions of small watersheds and forests around the Danjiangkou Reservoir in Hubei Province. Combined with the division of sub-watersheds within the small watersheds, water quality sampling was conducted. The main land-use and landscape factors affecting small watershed water quality were identified through methods such as correlation analysis and redundancy analysis. A method for predicting watershed water quality based on small watershed land use types and landscape pattern indices was developed. Vegetation buffer zones were constructed in riparian areas, and the suitable slope and width for the construction of riparian vegetation buffer zones were determined. Based on the water-holding capacity of litter and soil layers, guidance for the construction of forest stands suitable for water conservation was developed.
