摘要
以铁路交通快速发展为背景,运用层次分析法,构建景观生态评价体系,以景观生态结构、景观生态稳定性、景观生态质量为准则层,选取16项研究指标为指标层,对株洲县京广铁路沿线景观进行景观生态评价分析.研究结果表明:景观生态结构上,株洲县京广铁路沿线区域生态结构良好,其中自然度为2.46,路网密度为0.034 2,企业密度为0.027,自然度较高,路网密度小,景观斑块之间联系密切,但人类干扰度较大;景观生态稳定性上,其景观均匀度指数为0.906,多样性指数为0.543,优势度指数为-0.65,生态稳定性一般,景观斑块在区域内分布均匀,但景观斑块类型构成简单,多样性较小,景观优势度较低,景观生态系统脆弱,将影响区域整体稳定性;景观生态质量上,株洲县京广铁路沿线各景观斑块生态质量有所差别,其中林地生态质量最好,其次为耕地与水域,综合结果指数都大于0.80,而城乡建设与道路用地生态质量最差.最后,根据上述分析结果提出了相关建设建议.
Taking the rapid development of the railway traffic as background a landscape ecological assessment system was constructed using the Analytic Hierarchy Process (AHP).Taking the landscape ecological structure,the landscape ecological stability and the landscape ecological quality as criterion layer,and 16 research indicators were selected as the indicator layers to conduct the landscape ecological assessment and analysis of along the Jing-Guang railway in Zhuzhou county.the results show that: In terms of the landscape ecological structure,the ecological structure along the Jing-Guang railway in Zhuzhou county is good,with a natural degree of 2.46,a road network density of 0.0342,an enterprise density of 0.027,a high degree of naturalness,a small road network density,and a close connection between the landscape patches,but human interference is greater; In terms of the landscape ecological stability,the landscape evenness index is 0.906,the diversity index is 0.543,and the dominance index is -0.65.The ecological stability is general.The landscape patches are evenly distributed within the area,but the landscape patch types are simple in structure.With less diversity,less landscape dominance,and the fragile landscape ecosystem,the overall stability of the region will be affected; In terms of the landscape ecological quality,the ecological quality of the landscape patches along the Jing-Guang railway in Zhuzhou county is different,among which the ecological quality of the forest land is the best,followed by the cultivated land and the water area which the comprehensive outcome index is greater than 0.80,and the ecological quality of urban and rural construction and road land is the worst.According to the above analysis results the relevant construction suggestions are proposed.
