Technology Research Of Roof Tree Planting In PRD

With the first tree planting project of overburden roof took place in Guangzhou Dongfang Hotel(in the 1970s),Chinese overburden roof green construction began in the 1960 s. The Pearl River Delta(PRD)is the earlier place where the local construction techniques, planting levels have reached leading level in domestic,it can be used as domestic overburden roof tree planting’s typical reference. At present, the Pearl River Delta region has come out a large number of tree planting on overburden roof,cases produced was also reflected in the local green specification, but the system of process and complete theory is in shortage. In this background, the author points out the necessity for regional research on overburden roof tree planting, and hope that can conclude certain reference through the relevant dicussion.What the paper focus on is how to make sure the tree grow well under extreme environments which the roof is far from real soil. Faced with major issues, the idea of this paper is divided into four steps: First, a clear understanding of the overburden roof background、 current research situation; Secondly, summed out the foreign advanced technology and experience which would be a reference later; Then take the Pearl River Delta region as the basis of research, summarize the relevant local experience, plus with the foreign advanced and regional characteristics; Finally, with the actual project to discuss the choice of tree planting and other relevant aspects of technology, and this project can be as an object tested for the experience previously summed up.This paper aims to make up the lack of domestic overburden roof tree cultivation theory and hope to provide some reasonable reference for overburden roof tree planting. By providing a rational and reasonable alternatives for the overburden roof trees and providing sophisticated planting techniques and post-conservation management practices, thus can ensure the survival rate of trees on overburden roof.
