摘要
2011年,对黄河龙口库区植物区系成分进行了调查与深入析研究。表明:库区有野生维管植物283种,隶属于182属,63科;库区野生植物生活型、水分生态类型、区系地理成分与周围地带性植被相一致,但又表现出中生化的趋势和生境多样性、物种多样性增加趋势;水库工程建设对库区生态环境质量改善是有益的,但是人为干扰导致了植被的自我恢复演替,需要加强对区域生态环境的监管与治理,加速修复进度,避免过度开发。
The floristic analysis of Long Kou reservoir area in the Yellow River was investigated and studied in 2011,shows that: There were 283 species of wild vascular plants,belonging to 182 genera,63 families. The life type,water ecological type and the floristic geographical elements were consistented with the surrounding vegetation; At the same time,the mesophyte trends and a increase tendency in habitat diversity and species diversity were exist. It was beneficial to construction the reservoir project to improving the ecological environment quality,but the self restoration succession of vegetation was resulted by human disturbance; so in order to protect the regional ecological environment,we need to strengthen the supervision and management,to accelerate the speed of repairing,and to avoid the overdevelopment.
