南宁地区石灰岩山地生态设计初探

STUDY ON THE ECODEVICE OF THE LIMESTONE HILLS IN NANNING AREA

南宁地区石灰岩山地多为荒山草坡，开发利用非常困难．根据景观生态学的“共生”原则，利用生物控制的方法，从当地植物种群中优选了一系列耐旱、耐瘠、速生、固氮的品种，提出了建立以新银合欢为主的植物群落的生态建设方案．

The limestone hills in Nanning area are mostly barren,and it is very difficult to explore.According to the theories of Landscape Ecology,this paper puts forward a biocybernetic symbiosis measure with the selected plants in Nanning area,such as Leucaena leucocephla,cv,salvador,Pterolobium punctatum,etc,which are droughtenduring,fastgrowing,poorsoilresistant,nitrogenfixing.
