摘要
绿洲是一类独特的生态系统 ,它具有独特的结构和功能 .杨树是构成新疆绿洲防护林体系的主要树种 .本文在对策勒绿洲杨树生理生态学特性研究的基础上 ,从水分生理和光合作用两方面对国内外研究杨树生理生态学特性的一些方法和手段进行了初步评述 ,以期这项工作在独特的绿洲系统内广泛开展 ,从而为优选绿洲防护林树种、优化防护林体系及确保绿洲的可持续发展提供一定的理论依据 .
Poplar is the main component species in shelter forest subsystem,which forms a special kind of ecosystem in oasis with particular structure and function.Based on the studies on the ecophysiological characteristics of poplars in the Cele oasis, a preliminary comment was given on the experimental methods used at home and abroad,aim ed to facilitate the further studies on the characteristics of ecophysiology of poplars in the oasis.In order to sustain the oasis ecosystem management,the theoretical bases were also discussed on the optimization of shelter forest structure and the selection of proper tree species.
