摘 要:在滩地杨树抑螺林12年轮伐期内,采取沿时间序列定位观测及以空间换时间的调查研究方法,对滩地杨树抑螺防病林的造林地选择、钉螺种群消长与水因子、林龄及整地措施的相关关系进行了研究,对滩地杨树林的防浪护堤、阻滞水流和泥沙、降低地下水位等生态效应进行了分析,对林下草本植物的物种多样性进行了动态监测和研究,为有螺滩地的综合治理和开发提供依据。Studies were carried out during the 12 years of rotation of poplar plantations grown in beaches of Dongting Lake using long-term based time series of observations and temporal and spatial analyses. The relations among site selection for plantations, dynamics of snail population, soil moisture, plantation age and site preparation methods were studied. The ecological effects of poplar plantations in wave defending and slope protection, slowing down water and mud flow, and lower underground water level were investigated. Dynamic monitoring and analyses of species diversity of herbaceous plants under the plantations were conducted. The studies provided theoretical basis for integrated management and development of the lakeside beaches.
