【摘要】 随着城市化进程的加快,人类活动对景观的结构产生了强烈的干扰,林地消失、森林破碎化程度加深导致景观连接度降低的现象日益明显。而城市森林生态廊道作为生态基础设施的重要内容,是构筑与支撑生态环境的自然基础和城市可持续发展的重要保障。此外,在城乡中运用森林生态廊道提高景观连接度的方法来保证野生动物较低阻力的迁徙具有一定的生态意义和示范作用。本文提出了如何应用费用距离模型(least-cost)来构建生态廊道的方法。包括生态廊道构建中节点的选取、廊道的识别等关键步骤。解决由人类和自然干扰造成的景观连接度降低阻碍生物题在源斑块间运动的问题。并以哈尔滨市阿城区为例,在市域范围内构建180条生态廊道,使得景观资源在结构和功能上得到优化,从而提高景观连接度,保障森林生物自由迁徒。更多还原

【Abstract】 With the process of urbanization,the structure of human activities on landscape produced strong interference:forest fragmentation deepen the loss of landscape connection.The urban forest ecological corridor is an important content of ecological infrastructure.In addition,the use of forest ecological corridor in the urban and rural improved the landscape connection to ensure wildlife migration has a certain ecological significance.This paper show us how to use least-cost model(further- cost) method to construct the ecological corridor.Including the selection of nodes in the process of building the ecological corridor,corridor recognition of the key steps.Solving the connection degree caused by the human and the natural landscape reduce obstacles to movement between biological problems in the source plaques.As a case study of Harbin A Cheng,within the scope of the area build180 ecological corridors,to improve the landscape connection degree,safeguard the migration of the animals.更多还原
