Practice of re-greening management of high and steep rocky slopes on an island in a sea area of south Zhejiang
China's coastal islands and reefs are widely distributed,primitive island hills must have high and steep rocky slopes during construction.From the perspective of eco-environmental protection,the re-greening and management of high and steep rocky slopes on island reefs are necessary.The island environment is special,with frequent typhoons and heavy rains,accompanied by high sunshine hours and high transpiration environmental conditions all year round.Taking the re-greening project of a high and steep rocky slope on a sea island in South Zhejiang as an example,the site-specific re-greening engineering practices for high and steep rocky slopes in marine areas were proposed.The measure of square wooden bars&anti-slip nutrient bars&retaining wings was used to solve the problem of substrate scouring under strong rainfall weather.The re-greening plant species were determined by the nine selection principles.The intelligent automatic sprinkler irrigation system was introduced to irrigate slope vegetation.It not only improved the efficiency of sprinkler irrigation and solved the problem of high environmental evapotranspiration,but also avoided the traditional manual sprinkler irrigation operation which was highly dangerous on high and steep slopes.The island's high and steep rocky slope re-greening management project innovatively introduces an intelligent sprinkler irrigation system.And proposing effective and efficient re-greening and management programs in conjunction with the actual works,this re-greening management practice has some engineering reference significance.
