The Primary Ecological Theory and Its Application on the Construction of the Eco-sight Forest Belt

文章论述生态景观林带建设的主要生态学理论及其应用。在广东省生态景观林带建设中应该以群落生态演替的观点进行生态景观带(面)的建设,应用基于演替原理得出的生态恢复参照系来指导;按群落学的观点进行景观节点(点)建设,依据群落学和生物多样性原理,建立多乔木、灌木、草本、藤本等植物组成的景观节点群落,以作为景观线带物种的补偿地;以生态美学与生物多样性的观点进行绿化景观林带(线)的建设,利用群落的时间格局进行绿化景观林带生态美学的构建,利用群落的空间格局进行绿化景观林带的生物多样性构建;可应用边缘效应原理和种间相互作用原理来构建与管理生态景观林带。

The principle ecological theory and its application on the construction of the eco-sight forest belt are discussed in this paper. We maintained that construction of eco-sight forest belt （surface） in Guangdong province should follow the theory of community succession, so as to coincide with ecological restoration reference ; Con- struction of eco-sight node （point） should follow the community and biodiversity theory by incorporating diverse trees, shrubs, herbs and vines to enrich the species diversity of landscape belt; Construction of green landscape forest belt （line） should follow the theory of eco-aesthetics and biodiversity according to the differences in phenology along temporal scales and in morphology across spatial scales in order to construct green landscape belt with aesthetic value and high biodiversity. At last, we need to construct and manage ecological landscape forest belts basing on the theory of edge effect and the rules of interspecific interactions.
