Abstract:A health assessment technology in alpine meadow for grass-roots grassland managers,technicians and farmers has been developed.Taking the alpine meadow area of Tianzhu County,Gansu Province as an example,five grassland with different grazing intensity were selected to carry out the application of health status assessment technology.The ecological index (total coverage,the layer structure and wind/water erosion conditions) and the production index (total yield and edible grass proportion and new molehills/rat hole density) that reflects the health of the alpine meadow were selected for the study.Analytic hierarchy process (ahp) and data envelopment analysis method was used to calculate index right of restructuring.The optimal index set is constructed by applying the method of grey correlation degree.The corresponding index data were obtained by visual observation,step survey,and dry weight rank method.The results showed that the weight of each index was as follows:total coverage (0.232),community layer structure (0.341),wind/water erosion (0.277),total forage yield (0.103),edible forage ratio (0.037),new rodent mounds or holes density(0.011).The health evaluation results of five different grazing intensities (A1-A5) were as follows:A1 sub-health (68 points),A2 health (80 points), A3 sub-health (79 points),A4 sub-health (74 points) and A5 warning (55 points).The grassland health assessment technology in this study is convenient for grass-roots grassland managers,technicians and farmers to monitor and evaluate the health status of alpine meadow to be monitored.
