草地退化程度诊断系列问题探讨及研究展望

草地退化程度诊断是退化草地生态系统恢复和重建的前提和基础。对草地生态系统退化程度诊断流程中的各个环节进行了总结和讨论,从结构和功能两个方面建立草地生态系统退化程度诊断指标体系,并提出了通过结构途径与功能途径结合的方法来对退化生态系统进行综合诊断的思路。同时,提出草地退化程度诊断存在的问题及今后研究的重点发展方向。

Diagnosis of Grassland Degradation Degree and Its Perspectives

Diagnosis of degradation degree of grassland ecosystem is the basis and the precondition of ecological restoration.On this basis the procedure of diagnosis for degradation degree of grasslands ecosystem was given,and grassland degradation indices from both structures and functions were established,and the idea that integrated diagnosis on degraded ecosystem through combining structure way and function way were proposed.At the same time,the future focus direction of the study on diagnosis of degradation degree of grassland ecosystem was discussed.
