- 摘要:
- 对建设工程迹地岩土坡植被营造技术进行了探讨，认为应根据岩土坡的不同类型采取不同的植被营造技术措施。在植被营造过程中，始终采用林、草、藤结合模式，加强坡面植被多层次覆盖，起到明显的蓄水保土的效果。据测定，植被营造之后，暴雨平均减少径流量15.5%，保沙率41.0%；大雨平均减少径流量26.7%，保沙率64.0%；中雨平均减少径流量32.0%，保沙率73.0%；小雨平均减少径流量75.0%，保沙率100%。
- Abstract:
- The experiment shows that the revegetation of rock/soil hillside fields emerged after construction projects must stick to combination planting of tree-bush-grass-vine,and integrate the mixed vegetation with the one-species-vegetation.Multi-species vegetation mixture promote plant growth to each other,which is also good for the soil condition,and in turn,promote the growth of vegetation.Different hillside fields should be vegetated with different plants.For example,vine for rock hillside,Molasses Grass(Melinis minutiflora Beau.) for hillside covered with soil,which has the effect of nitrogen fixation and soil condition promotion,is a way to reduce material input.The most important aspect of this kind plantation is the problems of vegetation replacement are solved and with the effect of saving of money,manpower and seedlings,and with the effect of environment enhancing.The spot investigation shows that the average number of the soil erosion reduced by revegetation in torrential rain,heavy rain,moderate rain and light rain is 41%,64%,73% and 100% respectively;the water erosion reduced by revegetation in torrential rain,heavy rain,moderate rain and light rain 15.5%,26.7%,32% and 75% respectively.
