Calculation and Research on the Evaluation Model of Ecological Carrying Capacity of Shallow Mountain Area in Beijing

Principal component analysis was selected to define the weight value in the calculation of the evaluation model. Software SPSS was used to process raw data by calculation of correlated matrix in the index layer, and in the partial objective layer, the raw data was processed by the calculation of covariance matrix with software MATLAB. At last, the ecological carrying capacity and ecological stress of shallow mountain area in Beijing were calculated, which provided a method to evaluate sustainable development of shallow mountain area in Beijing.
