北京市正规垃圾填埋场恢复植被特征
Characteristics of Vegetation Restored in Regular Garbage Landfills in Beijing
摘要
Abstract
With the development of the city and the progress of the ecological civilization,the restoration of the waste land in the landfill has become a hot issue in scientific research. Through the vegetation investigation and analysis of the four landfills in flat land and one mountain valley landfill in Beijing,it found the length of the closure time has an important influence on the restoration of vegetation in the waste dump of the township plain landfill.The coverage area of the shallow root shrubs and trees increases with the increase of the closure time, and the cover layer is naturalized. As for mountain valley landfill near-natural vegetation with artificial cultivation takes a relatively higher proportion,such as coniferous forest with the dominate species Platycladus orientalis, deciduous broad-leaved forest with native species Crataegus pinnatifida, Ulmus pumila, etc as dominate species; deciduous broad-leaved shrubs with Vitex negundo, Myripnois dioica, etc, as dominate species, ground cover plants are all wild species. Plain landfills should follow the ecological views about low maintenance and natural succession with the order of"herb-shrub-arbor". The mountain type should be selected and configured in combination with the vegetation investigation,especially the natural origin species,to accelerate the stability of the community.关键词
