基于GIS的鄂北调水工程沿线及其核心区域景观综合评价研究

Landscape Evaluation of the Northern Hubei Water Transfer Project and Its Core Areas Based on GIS

以鄂北调水工程沿线及其核心区域为研究对象,采用层次分析法(AHP法)建立了以景观生态评价、景观美学评价和景观人文评价为准则层的景观综合评价指标体系,利用ArcMap的空间叠加分析功能对各基础评价指标进行叠加分析处理,完成对研究区域景观质量的综合评价。结果表明:鄂北调水工程沿线及其核心区域景观综合质量的差异较明显,其中纪洪明渠至孟楼—七方倒虹吸段、白河管桥段、花儿山隧洞至兴隆—万福隧洞段、广水区段等区段景观的综合质量较差,而丹江口水库处、沙河渡槽段、东郊(优良)明渠段、封江口水库处以及王家冲水库处等区段景观的综合质量较好,该结果能较准确、客观地反映鄂北调水工程沿线及其核心区域景观的实际情况。在此基础上,提出了提升调水工程沿线及其核心区域景观质量的措施,可为沿线景观资源的保护、开发和利用提供科学依据。

This paper takes the area along the Northern Hubei water transfer project and its core areas as the research object,and uses Analytic Hierarchy Process(AHP method)to establish a landscape evaluation system with landscape ecological evaluation,aesthetics evaluation and landscape humanistic evaluation as the criterion layer,and uses GIS spatial overlay analysis method to evaluate each evaluation factor,and finally completes the landscape evaluation of the study area.The results show that the landscape difference along the Northern Hubei water transfer project is obvious,among which,Jihong Open Channel to Menglou- Qifang Inverted Siphon section,Baihe Pipeline Bridge Section,Huaershan Tunnel to Xinglong- Wanfu Tunnel Section and Guangshui section,the comprehensive quality of them is relatively poor,while Danjiangkou Reservoir,Shahe Aqueduct,Dongjiao(Youliang)open channel,Fengjiangkou Reservoir and Wangjiachong Reservoir,the overall quality of the landscape is good.The results can reflect the actual situation of the landscape along the water transfer project more accurately and objectively.On this basis,the paper puts forward measures to improve the landscape quality along the water transfer project,which may provide a scientific basis for the protection,development and utilization of landscape resources along the line.
