太湖退化湖滨陆地系统生态修复效果评价研究
Ecological restoration technology of degraded lakeshore terrestrial system in Taihu Lake
摘要
Abstract
With the continuous development of social economy and the rapid increase of population,agricultural production activities in the Taihu Lake area had intensified.The water and land system of Taihu Lake was damaged,which posed a serious potential threat to the safety of the water environment and drinking water quality.In this study,Shaoxianggang and Baidugang in the Taihu Lake area were used as the research areas,and two different ecological restoration models of lakeshore land systems were established to explore their different ecological restoration effects.The results showed that:(1)Both the two ecological restoration technologies could effectively improve the soil quality.Among them,the Shaoxianggang ecological restoration system increased the maximum soil water holding capacity,capillary water holding capacity,minimum water holding capacity,total porosity,capillary porosity,soil available potassium,soil total potassium content,soil organic matter content and soil total nitrogen content by 29.80％,28.11％,30.82％,15.89％,14.40％,19.87％,16.73％,16.18％and 12.90％,respectively.(2)Different ecological restoration models of lakeshore terrestrial systems had different optimization effects on soil indicators.Shaoxianggang terrestrial system ecological restoration model had a better effect on improving soil physical indicators,while Baidugang terrestrial system ecological restoration model had a better effect on improving soil chemical properties.Therefore,when carrying out ecological restoration in the Taihu Lake area,appropriate ecological restoration technologies should be selected according to the main purpose of the period.关键词
