民勤荒漠生态区划研究

民勤属于典型荒漠化地区,20世纪50年代以来,当地以造林为主防沙治沙,然而生态环境持续恶化。民勤的荒漠化形式要求我们重新审视我们的荒漠生态对策。以民勤荒漠区为例对荒漠生态区划进行了初步探索,上与综合自然区划相衔接,下与区域规划相结合,增加了生态设计的内容,区划出了人为活动的区域、范围和干预的强度,因此更具体化、更具实际操作性。提出了一些荒漠生态区划方面必须坚持的原则,在建立指标体系时,考虑了人类活动的影响和资源利用方式,以及以节水和保护水资源为中心和以封育保护为主的荒漠生态对策。

Ecological regionalization of Minqin desert in Gansu

Minqin county is a typical desert areas,Since 20th century 50's,The local government tried to combat desertification by forestation,however,the ecological environment deteriorate continually,our countermeasure on desert ecology requested to scan by the posture of desertification in Minqin.This paper has made the preliminary discussion on ecological regionalization on desert in Minqin desert area,it be joined up by comprehensive physical regionalization and be joined down by regional planning,add ecology design,and divided the region of human activities,the scope and intensity of intervention.Therefore, it is more concrete and more practical operability.This paper also proposed some principles that must be persisted in ecological regionalization of desert,the influence of human activity and the resources use should be considered when establish the indicator system,we should put water saving and protection of water resources at the center,and use enclosure as the mainly desert ecosystem protective measure.
