退化草地生态恢复研究案例综合分析:年限、效果和方法
Synthesis-review for research cases of grassland ecological restoration: Years, effect and method
摘要
Abstract
The degradation and deterioration of grassland ecosystem had influenced the global ecological security,local resident livelihood and development of culture diversity in rangeland area.The restoration projects successful depend on the good experience provided by effective study case,and then those cases normally are with different study years.And the study case with different years have different indicators or guidelines for the restoration goal,method.Moreover,the long-term in the grassland restoration study is seen very important for getting more experience.This paper had reviewed 149 international study cases of grassland restoration with different study period,and analysis the study time pattern,restoring goal,restoring method,and restoration effect,and the long-term data getting method etc,and we had several summary points in the following context.(1) In the 149 cases,the most cases were less 10 years,that focus on continuous experiment every years,and on the other hand,the long-term study cases (＞10 years) rely on the filed revisiting.(2) The study with long-term monitoring and survey has more reliability in the results,and have more useful guideline of restoration technique.In normal,the study objective with the productivity had less study period (years) than that with the objective of ecological function.(3) In those study cases,three most restoration goals were biodiversity,vegetation coverage,and soil carbon pool.(4) There were few cases about animal community.(5) The most restoration method or approach applied in the study were seed sowing,fencing exclusion,and grazing.(6) The study with longer time (years) in the grassland restoration applied the method of field revisiting to get the data from same filed sites could be compared with previous records.As the conclusion,the authors suggested that we should pay attention to the application of field revisiting method in monitoring and evaluation of grassland restoration's effect.We should conduct more and more the on-site field measurement and then do the data analysis,and big-data synthesis then their result will be more effective.关键词
