摘要
对许多涉及生态过程重大科学问题的认知,使长期生态学的研究在国际上受到越来越多的重视。长期定位观测也是系统地了解荒漠生态系统过程,获取基础数据的主要手段和有效途径,但是国内已有的定位观测站点的观测指标各成体系,不利于数据比较和信息共享。本文按照继承性、系统性、代表性和可行性的原则制定了比较完整可行的适合我国荒漠生态系统定位观测,包括水、土、气、生的综合指标体系,以期为荒漠生态系统定位观测工作的规范化打下一个坚实的基础。
People give more and more values on the research of long-term ecology in world while there are more and more cognitions about rmny vital scientific questions of ecology process. The long-term localization observation is the main method and the effective way to systermtically understand desert ecosystem process and to obtain the basic data for desert ecosystem. For long time there are different index systems used by different localization observation stations and it＇s difficult to make information share. In this paper an integrated index system which includes hydrology index, soil index, meteorology index and biology index was set up as a base work for the standardization of the spot monitoring research of China.
