安徽省宁国市元竹枯死原因与防治对策研究

文章探讨了安徽省宁国市中溪镇元竹大面积枯死的原因.在现场调查、污染监测和综合分析的基础上,排除了污染、病虫害致死和元竹而开花死亡的可能性,得出该区元竹枯死是由于非污染生态工程道路改建、水利水电工程和河道采砂等人为活动所导致元竹区的局部生态系统破坏,致使该区地下水位的不正常变动,从而引起大面积不规则分布的元竹干枯或浸泡死亡.文中最后根据该区生态环境状况,给出了防治元竹枯死的生态对策与建议,为防治其它地区的元竹枯死提供了参考和经验.

A Study on Phylostachys Meyeri McClure Death and Countermeasures of Ningguo County Anhui Province

The reason of Phylostachys meyeri McClure death in the large area of Zhongxi town Ningguo county Anhui Province is discussed in the study. On the basis of fieldwork, pollution monitoring and integrative analysis, the posibility of Phylostachys meyeri McClure death as a result of being polluted, bringing diseases and insect pests and blossoming out could be excluded. The primary study shows that Phylostachys meyeri McClure death was caused mainly by artificial activities including road building, hydrology electricity station constructing and riverway excavation. The activities distroiated the local ecosystem eqiulibrame and brought a series of changes on ground water level. Phylostachys meyeri McClure died in this area since the ground water level changing. In last of the paper, some countermeasures for prenventing Phylostachys meyeri McClure death are put forward according to the situation of ecological environment, such as stoping sand colloction on the river channel, rehabilitating some ecosystem, and adjusting the ground water level.
