九龙江流域的水土流失与治理

Soil and Water Loss and Its Control in the Jiulong River Basin

九龙江流域(漳州段)水土流失面积956.1km2,占土地总面积的14.13%。水土流失导致土壤退化、旱涝灾害频繁、河床抬高、水利设施被毁等严重问题,日益引起九龙江流域群众及各级政府的重视。根据漳州段水土流失现状,规划"十五"期间治理水土流失面积200km2,2006—2015年治理水土流失面积300km2,2016—2030年治理水土流失面积400km2。治理上,要推广成功的小流域综合治理模式,特别重视坡地果园的水土流失治理。

An area of 956.1 km2 is effected by soil loss in the Jiulong river basin, covering 14.13% of the total land area. Soil and water loss has resulted in severe problems such as soil degeneration, frequent drought and flood, river bed aggradation and damage to water conservancy facilities, which have been emphasized by the people and government of all levels in Jiulong river basin. The control targets of the Jiulong river are as follows: controlling soil loss from 200 km2 of land during the period of 'the 10 thfive years', 300 km2 during the period of 2006-2015, and 400 km2 during the period of 2016-2030. For soil and water conservation in the Jiulong river basin, extending the comprehensive controlling patterns of small watersheds and harnessing orchard soil and water losses are very important.
