林业有害生物防治压力区域差异及影响因素分析

【目的】林业有害生物防治面临区域差异化的压力,加重了森林资源的经济与生态损失。测度我国林业有害生物防治压力及其影响因素,探索防治压力的区域分布特征,从而针对性地提出优化措施。【方法】分析林业有害生物防治压力现状,利用聚类分析法将各省份防治压力分成3类,结合面板校正标准误模型评价产生防治压力的原因及影响因素,并与防治率及无公害防治率一同呈现于地图,进行区域差异特征比较。【结果】我国林业有害生物危害的总体防治压力较重,减灾机制只能在一半程度上缓解灾害暴发的扩散趋势,投入资金的使用效率严重不足,从业人员及机构数量尚不能满足区域化防治压力需求,且管理机制存在一定的“马太效应”,“胡线”西部生态化防治意识较弱,目前采取的措施不足以缓解较大的防治压力。【结论】针对区域发展需求完善基础设施建设,提高从业人员专业化水平,调动社会力量构建社会化防治组织,缓解区域差异及政府防治压力,保障森林资源和国家生态安全。

The spatially differentiated factors of forest pest control pressure

【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.
