| 摘 要： | 在半干旱地区水资源是植被生态建设的主要限制因子,也是农牧交错区生态恢复与重建的根本。本文根据坝上各县水资源调查资料,分析了水资源在坝上的时空分布特征、与光温资源的耦合程度;探讨了水资源的分布规律对植被生长与分布的影响。研究认为坝上应以自然恢复为主,林草植被恢复建设则应以地带性植被分布规律为依据,以水定草、定林,实现土壤水分的持续利用。

| Abstract: | Water resource is an important limited reason in ecological construction of vegetation in half-aridity region,as well as the foundation of ecological rehabilitation and reconstruction in Agri-Grazing-Ecotone.By the spot investigation of water resources of Bashing Plateau,this research analyzed space-time distributing character of water resources of Bashing,and the coupling combination wity radiation and heat resources are analyzed.Then the possible impacts of water resource distributing rule on vegetation growth and distribution are discussed.The results show that natural rehabilitation is the important mode,and the other mode-ecological rehabilitation of forest and grass must conform to vegetation distributing rule,and must be on the base of water resource situation in order to realize sustainable use of soil water. |
