中文摘要: |
本文以建立和谐生态的高产稳产农田为目标,提出了一套盐碱地综合治理生态恢复综合评价指标体系。该体系包括:土壤指标、生境指标、生物指标、生产力指标和可持续发展指标等。把层次分析法(AHP)与矩阵实验室MATLAB结合,确定评价指标的权重;针对定量和定性指标,分别运用了无量纲法和分级打分法,建立了综合评价数学模型。最后,对陕西渭河流域的卤泊滩盐碱地和谐生态治理实践进行评价,结果表明,该评价指标体系具有良好的适用性。 |
英文摘要: |
Aiming at the objective of establishing stable high yield farmland and establishing a harmonious ecosystem, an assessment system for comprehensive restoration of saline land is proposed. The indexes of this system include soil index, eco environment index, ecology index, productivity index and sustainable development index. The weights of these indexes are determined by means of analytic hierarchy process (AHP) combining with MATLAB. The dimensionless method and giving mark method are used to quantitatively or qualitatively determine the indexes respectively for establishing the assessment model. The assessment system is applied to assess the effect of ecological restoration in Lupotan saline land, Weihe River basin. The result indicates that the proposed system is feasible and reasonable. |
