Based on the time process and spatial perspective of seventeen townships in Zoige County,the evaluation factor of the Resources and environment carrying capacity is selected by the qualitative analysis method,the evaluation index system is determined and the evaluation weight of each factor factor is quantitatively analyzed.The comprehensive index method is applied to evaluate the carrying capacity of resources and environment in Zoige county from 2010 to 2017 and analyze the spatio-temporal process.The status of force is evaluated and spatio-temporal process analysis is carried out.Based on the scenario analysis,the development trend of population,farmers' income,grassland resources and woodland resources in Zoige County in 2020 was predicted.Based on the short board theory,the Resources and environment carrying capacity of Zoige county was early warning.The following conclusions are drawn:(1)From the natural bearing capacity support system,the support system of resource carrying capacity,the support system of environmental carrying capacity and the support system of social and economic bearing capacity,20 evaluation indexes are selected,the weight of each index is calculated by entropy method.From the ranking of index weights,the supporting system of resource carrying capacity is the most important factor for the stable development of comprehensive bearing capacity in Zoige county.Through the calculation and extraction of the index of the four bearing capacity supporting system of the carrying capacity of the resources and environment,the index of the villages and towns under the support system of different carrying capacity is obtained.The evaluation results of the Resources and environment carrying capacity of the county are remitted.(2)Through the analysis of the spatio-temporal process of the evaluation results of the resources and environmental bearing capacity of Zoige County,the temporal and spatial variation is obtained.On the time scale,the overall index of the comprehensive index of the carrying capacity of resources and environment in Zoige county shows a slightly rising trend in the past 8 years,and its variation degree is not significant.In terms of spatial scale,the overall change of the comprehensive index of resources and environmental carrying capacity in Zoige showed the spatial differentiation characteristics of “higher in north and east,lower in south and west”.From the change of specific index,the high regional Resources and environment carrying capacity of the support system of resource carrying capacity and the support system of environmental carrying capacity are relatively higher,and the Resources and environment carrying capacity of the weak resource carrying capacity support system are relatively weak.The resources and environmental bearing capacity of Zoige county has great difference between different towns and towns,and there are also great differences between the supporting systems,and the spatial differentiation of the bearing support system is obvious,which has the characteristics of obvious spatial change and large regional distribution.(3)Forecast and early warning analysis of Zoige County in 2020.The results show that in 2020,the overall environmental bearing capacity of Zoige county has a "general" state,and the overall resource environment is not "early warning".There is little pressure on the bearing capacity.The distribution of early warning state is similar to the distribution of resources and environmental carrying capacity,and it shows "higher in east,lower in west" in space.With the implementation of the environmental protection policy in the northwest of China in the western development,the future Resources and environment carrying capacity of Zoige county will gradually become better.In the future,the development of Zoige county should pay attention to the regional optimization in the county,and strengthen the protection of resources and the industrial transfer.
