    摘要:

    土地整理生态效益是指因土地整理项目实施后项目区的土壤、微地形地貌、水文、植被等生态环境因子变化带来其生态系统服务功能的价值的变化。土地整理能够改变土地利用方式,改善土壤理化性质,其结果直接影响有效耕地面积和耕地质量,同时对区域生态环境有一定的影响。因此,评价和分析土地整理项目的生态环境影响具有重要意义。本文以河北省望都县土地整理项目为例,将耕地质量指标、植被防护指标、土地利用指标中的7个指标分别定量,运用层次分析法确定本次评价中耕地质量指标、植被防护指标、土地利用指标的权重分别为0.24、0.623、0.137,建立生态效益评价模型,得到耕地质量指标、植被防护指标、土地利用指标的量化评价结果。通过对评价结果的对比分析,能够客观、有效地反映土地整理项目生态效益,提出提高土地开发整理生态效益的对策和建议,为土地整理实践提供科学的参考依据。分别以农地和林地两种用地情况占主要因子,通过分析各区的土地利用特点,为研究区农业区划及土地资源利用提供科学依据。

    Abstract:

    Ecological benefits of land consolidation is a result of the soil micro-topography, hydrology, vegetation, and other environmental factors of changes in ecosystem services after land consolidation project and their value changes.Land consolidation is about to change land usage, to improve soil physical and chemical properties.The results of a direct impact on the effective cultivated area and quality of arable land have a certain impact on the regional ecological environment.Therefore, evaluation and analysis of land consolidation is of great significance.In this paper, taking land consolidation project in Wangdu County as an example, indicators of land quality, indicators of vegetation protection, and indicators of land use were determined.By using of AHP, this three indicators’ weight were 0.240, 0.623, and 0.137.The eco-efficiency model was established, and land quality indicators, indicators of vegetation protection, land use indicators were quantitatively evaluated.Comparing the results of evaluation can objectively and effectively reflect the ecological benefits of land consolidation project.This is useful in select land consolidation measures and proposals.Analysis of character of land usage of farming land and forest land provided scientific basis for studying agricultural distribution and land consolidation.
