Study on Disturbances and Its Effects on Nature Reserves

As a widespread natural phenomenon, disturbances are considered a discrete event occurring in a natural ecosystem within various spatial and temporal scales. The present paper discusses the types of disturbances and their influence on the ecologic system in nature reserves. It is shown that nature reserves are facing a great challenge dealing with these disturbances. A rational control for disturbances should be improved in order to promote the healthy development of nature reserves this could be done by enhancing the publicity and training of environment protection, coupling management with communities around and other nature reserves, effective management methods, rational planning, and supporting nature servers.

中国森林资源的动态演变和现状及储备的战略构想

从中国森林资源的动态演变及其现状出发,以相关的统计资料为基础,从理论角度分析了森林资源储备问题。认为森林资源储备的实质是森林资源在时间上和空间上动态的均衡配置过程,是一种在时空尺度上的森林数量和质量的动态变化过程。森林资源的储备不仅是数量(规模)的储备,还应包括质量的储备,并将其划分为生态性森林资源的储备和经济性森林资源的储备。认为森林资源储备的最终目标是要实现一种"前沿森林"状态。提出森林资源储备的主体应实行政府主导,企业、个人等多方参与的多元化主体。同时,应该建立国家森林资源储备制度,包括制定森林资源储备法案,设立森林资源储备的专项基金等,来保障森林资源储备的有效实施。
