岩溶山区石漠化生态治理的生态效应研究
Ecological Effects in Ecological Management of Rocky Desertification in Karst Mountain Region
摘要
Abstract
The change of soil physicochemical property and vegetation quantity attributes in Huajiang canyon demonstration area of ecological management of rocky desertification in Guizhou Province during the period from 2005 to 2009 was analyzed.The results indicated that：（1） The coefficient of variation of soil physicochemical properties reduced,suggesting its spatial variation degree decreased.（2） The soil total porosity slightly declined;the soil non-capillary porosity significantly increased;the soil capillary porosity and the soil capillary capacity decrease markedly;the soil field capacity rose obviously,indicating that soil porosity configuration became more rational.（3） Change of organic matter content was not distinct.Total nitrogen and total phosphorus significantly increased but total potassium decreased.Meawhile,soil pH value slightly decreased.（4） The height,base diameter,crown diameter and evenness of plants increased prominently.The ecological efficiency of soil quality and plant community was preferably coherent.All above results illustrate that the soil and plant ecological efficiency have been improved,which ameliorate the environments in rocky desertification of ecological management areas in karst mountainous region.关键词
