摘 要:以黑牛河小流域为例,在详细分析东北低山丘陵区小流域可持续发展现状的基础上,对该小流域的可持续发展状况进行定量评价:从效益显著性、资源与环境可支撑性和系统运行稳定性3个方面,选择31个因素作为参评因子,建立评价指标体系;采用精度较高的均方差法确定指标权重,以消除人为经验主观判断,提高评价的客观性和准确率;运用递阶多层次综合法建立二级层次指标(效益显著性、资源与环境可支撑性和系统运行稳定性)评价模型,多目标线性加权函数法建立流域系统综合评价模型,评判出了该区小流域的二级层次指标和综合指标的可持续发展水平,并有针对性的提出了小流域可持续发展的具体对策和建议。This paper conducts a quantitative estimation of sustainable development status in small watershed taking Heiniuhe river as an example. Thirty-one factors were chosen from three aspects of benefit remarkability (BR), resource and environment supportability (RES) and system functional stability (SFS) and evaluation indicator was built. The mean square difference method which has a relatively high precision was introduced to ensure the index weight, avoid the subjective judgment with artificial experience and improve the objectivity and accuracy. A two-step hierarchical indicator (BR, RES, SFS) evaluation model was built using multi-hierarchical synthetic method, and a drainage system integrated evaluation model was set up using multi-objective linear weight function method. The two-step hierarchical indicator and synthetic indicator were identified for evaluating sustainable development level of this watershed. Countermeasures and suggestions specially for small watershed sustainable development were put forward.
