从景观异质性分析近自然森林经营

Analysis of Nature-Approximation Forest Management with Landscape Heterogeneity Theory

从景观生态学的核心理论——景观异质性理论着手分析了近自然森林经营模式 :其本质是对森林景观异质性的维持和促进 ,是森林经营学发展的一种历史必然 ,具有充分利用异质时空 ,提高森林系统生产力、生物多样性、景观多样性 ,增强系统抗干扰性和稳定性等诸多优点 ,从而有利于森林的可持续发展。

Heterogeneity forest landscape is decided by variable environment, vegetation natural successional change and impact of human and nature. Based on the analysis of natural forest management with heterogeneity theory which is the main point of landscape ecology, it showed that the essence of nature-approximation forest management is to maintain and accelerate its heterogeneity and it can utilize the variable environment efficiently, increase the forest ecosystem fertility, improve the biological diversity, enhance the ecosystem stability and advantage to the forest sustainable development.
