京郊琉璃河河岸带土壤生物工程的生态效应

Ecological Effects of Soil Bioengineering in Beijing Riparian Zone of Liulihe River

以北京市怀柔区琉璃河示范区为研究对象,从土壤生物工程的生物量、河岸带的生物多样性、温湿度的调节等方面研究了土壤生物工程实施2a后对河岸带的改善作用。结果表明,土壤生物工程实施后,植物根系生长良好,改善了土壤的抗侵蚀性;增加了生物多样性;土壤生物工程各种措施对温度和温湿指数具有良好的作用。

Riparian ecological management is an important part of the governance of rivers. This paper stud- ied the soil bioengineering two years after the implementation of the improvement of the riparian zone, mainly studied the biomass of soil bioengineering and riparian biodiversity,temperature and humidity regu- lation. The results showed that the implementation of soil bioengineering improved the corrosion resistance of the soil, increased biodiversity, and adjusted the role of temperature and thermo hygrometric index （THI）.
