Study On The Greening Model Of Plain In The Pearl River Delta Of China

The development history of afforestation in plain can be traced back to the period of written records,from the initial planting of trees,to the present multi-level,multi-structure,multi-functional system engineering.The Pearl River Delta area of Guangdong province has the advantages of natural geographical conditions and obvious geographical advantages.It is suitable for the construction of plain greening trees,and has the advantages of carrying out plain green favourable co nstructions.Therefore,construction conforms to the national conditions of the plain afforestation project,it has important practical significance to maintain the ecological security and regional area to enhance the greening level and ensure agricultural high and stable yield,improve the overall income of farmers,promoting the construction of new socialist countryside.In this paper,the greening of the plains in the Pearl River Delta region is taken as the object of study.The literature search method,the empirical research method,the expert consultation method and the TOPSIS method are studied.By fully consulting,summarizing and analyzing the relevant literatures at home and abroad,This paper analyzes the status quo,favorable conditions and unfavorable conditions of the plain greening in the Pearl River Delta,and makes a judgment on the development trend by using the theories of forestry,forest management,landscape ecology,forest aesthetics,system theory and forestry sustainable development.From the point,line and surface combined with the actual area of the Pearl River Delta are divided into six kinds of green space types;The paper discussed the application of the ideal solution and ordering method to the selection of plain greening tree species,and ranked one hundred and eighty-eight species suitable for greening of the plains of the Pearl River Delta.In this paper,three kinds of plant configurations and six kinds of plants were put forward,which provided the scientific basis for the cultivation of suitable trees and reasonable planting.Based on the six kinds of spatial greening types,this paper combined the selection of different plants in the plains of the Pearl River Delta with the selection of different plants,and extracted thirty-three sets of timber,ecology,landscape,and so on.According to the trend of social and economic development and forestry ecological construction in the Pearl River Delta region,Carbon sinks and other functions in one,respectively,for urban greening,village greening,farmland forest greening,road greening,water greening,wasteland green plain green typical model.And provide scientific basis and reference significance for plain greening in the Pearl River Delta region.
