Abstract:

【Objective】 As China is facing spatially differentiated forest pest control pressure, the economic and ecological losses of forest resources would increase. In this paper, we assessed the control pressure and its influencing factors, summarized the spatial features, and proposed advices to improve the outcomes. 【Method】 We first analyzed the current control pressure and divided the natural control pressure for each province into three degrees through the Cluster Analysis method; then, we examined the reasons and factors driving the spatial differentiation of the control pressure based on the panel calibration standard error model (PCSE). We depicted the final results on the map of China and compared them with the control rate and ecological control rate.【Result】 The results showed that China forest pest control is under huge pressure, as the recent control system could only recover half of the damage with low efficiency of the input fund utilization; in addition, the number of control workers and institutions are far from satisfying the regional control necessity. Moreover, according to the “Matthew Effect”, the ecological control awareness in the western part of “HU Huanyong” scored weaker than in the eastern part, while the control measures hardly satisfied the increased control pressure in the west. 【Conclusion】 Firstly, the government needs to provide the infrastructure according to regional development needs, and improve the professional skills of control workers. Then, socialized control organizations should be established by mobilizing social forces to diminish the regional differences and solitary governmental control pressure, while also reinforcing the ecological balance of natural resources.
