| 摘 要： | 水分是黄土高原半干旱区林草植被建设的主要限制因子。在借鉴前人进行林草植被建设取得的经验和教训的基础上,从水分与林草植被建设的相互效应出发,提出了以土壤水分平衡为核心的黄土高原林草植被建设3项措施:1)不同地带天然植被类型的林草植被建设;2)不同植被地带的水分生态条件和立地条件的林草植被建设;3)注重林草植被布局,加强草地建设。认为要提高林草植被的成活率、保存率和最大限度发挥林草植被的生态效益,黄土高原半干旱区林草植被建设必须要仿拟天然植被结构和遵循适地、适树、适草的原则进行,并探讨了今后进行林草植被建设的方向和措施。

| Abstract: | Water is the primary limiting factor for forest and grass vegetation construction in semi-acid soils of the Loess Plateau area.On the basis of forest and grass vegetation construction experiences and lessons acquired in past years,the authors have analyzed the influences of vegetation construction and water on each other,and have proposed three measures for forest and grass vegetation construction with water balance as a key feature.Our results show that attention must be paid to the 1) different types of natural vegetation;2) soil water status and soil texture conditions;3) forest and grass distribution and strengthened grassland construction.To improve vegetation construction survivability,conservation must simulate the natural vegetation configuration by selecting trees and grasses that are adapted to the native soils and environment.Finally the authors discuss the future direction and measures for forest and grass vegetation construction in the semi-acid areas of the Loess Plateau. |
