| 摘 要： | 首先从景观生态学角度分析了土地整理与生态环境的关系，认为土地整理各类工程对景观生态产生了干扰、演替等生态效应，形成了各种生态胁迫因子。将当前土地整理对生态环境的压力归纳为4个大类，即土地平整、植被破坏、沟渠路建设与零星地的归并以及作物种植与客土填充，从而构建了土地整理生态风险评价的概念模型。这个模型揭示和描述了土地整理绝大部分可能的风险源和胁迫因子以及这些风险源和胁迫因子可能产生的生态影响，为生态环境友好型土地整理模式的建立提供了科学依据。

| Abstract: | The relation between land consolidation and ecological environment from the prospective of landscape ecology was analyzed,considering that land consolidation produces ecological effects such as interference and succession etc and forms various ecological stress factors.The ecological environment pressure caused by land consolidation was summarized: land leveling,vegetation destruction,ditch and road construction,sprinkling land merging,crop planting and soil dressing filling.Then conceptual model for Ecolog... |
