Ecological Recovery In Highway Slopes

Along with the development in highway construction, the slope area also gradually enlargement every year, ecological recovery of highway slopes become a more important topic, particularly the ecological recovery of rock slope have become a widespread focus everyone. If we do the work of slopes recovery well, we can prevent the loss of water and soil effectively, strengthen the whole slopes, protect ecological environment in highway. In the more bad environment which mankind live, ecological recovery of highway have huge function. For a long time, China's highway construction attached importance only on technology and economic efficiency but not any a little on ecological environment protection, which has already taken its toll on our environment, so ecological environment in highway slopes have extensive foreground. The greening of highway slope have two conditions: the first is seeding matrix that plant grows on; another is how to fix seeding matrix on the slope. The key of ecological recovery on rock slope lies in the following: adaptive plant and collocation of the seeds; adaptive seeding matrix material and material ratio; adaptive technique of ecological recovery on rock slope. This text elaborates how to do these works well by experiments: According to the soil or the rock property,the nature condition on the region,various plant growth characteristic , we should choice perennial plant that have flourishing root, grow quickly, resist drought, bear poor conditions, Increment plant grows in the hometown。Assurance adaptive plant collocation of grass,bush and tree, spray many kinds of plant, Strengthen advantage, construction plant cluster in the hometown. According to the plant which we choose and the region condition, follow to economical principle, select material on the spot, Assurance seeding matrix material and ratio, According to rock property and slope ratio, Adopt adaptive technique of ecological recovery.
