摘要
研究目的:土地整理生态评价旨在为优化土地整理规划设计与实施,提高耕地质量提供科学依据。研究方法:以GIS为支撑,建立土地整理生态评价综合评价模型。研究结果:土地整理生态评价为提高土地整理规划设计与项目实施的科学性、针对性奠定了良好的基础。研究结论:利用GIS的空间分析功能,采用栅格作为评价单元,可实现土地整理生态环境的定量评价,为更好地开展土地整理工作提供理论依据和决策支持。
The paper aims at ecological assessm ent which is of great importance for o ptimizing planning of the land consolidation and improving th e quality of cultivated land.Method of modeling was employed.The ecolo-gical assessment can be solid and scientific basis both for land consolid ation planning and for the implement ation of land consolidation projects.Tak ing the advantage of spatial analyst function of GIS and by choosing grid a s assessment cell,the quantified ecological assessment in land consolid ation can be realized,which will pro vide theoretical basis and decision support for better land consolidation.
