摘要
河流岸线对河流沿线生物栖息、调蓄径流、蓄泄洪水等均具有重要意义,因此,应根据河流岸线特点来分析岸线资源开发的适宜性及发展潜力,探究河流岸线科学分类方法及开发阈值。针对河流岸线纵向及横向空间特征建立了评价指标体系,利用多准则多目标的数学方法,对岸线资源开发的适宜性进行了综合评价。在此基础上,以康县燕子河为实例进行了研究,即将河流岸线分为保护区、保留区、控制利用生产岸线、控制利用生活岸线、控制利用生态岸线、开发生产岸线、开发生活岸线以及开发生态岸线共8种发展适宜功能区,对其岸线适宜性功能定位及开发阈值进行了研究。研究结果表明:8个发展适宜功能区中,保护区和保留区不宜开发建设,控制利用区和开发利用区的开发阈值分别为60%~70%,70%~85%,发展潜力分别为40%~50%,90%~100%。研究结果可为岸线因地制宜发展、精细化管理及河流岸线资源的可持续开发利用提供一定的科学依据。
The river shoreline is of great significance to the biological habitat,regulation of rivers and flood storage and discharge.It is necessary to analyze the development suitability and potential of shoreline development,and explore the scientific classification methods and development thresholds according to the characteristics of river shoreline.This paper established an evaluation index system based on the vertical and horizontal spatial characteristics of river shoreline,and evaluated the development suitability using mathematical methods of multi-criteria and multi-objective.This paper took Yanzi River in Kang County as the research object.We divided the river shoreline into 8 kinds of development suitable function areas(protected area,reserved area,controlled industrial utilization shoreline,controlled livelihood use shoreline,controlled ecological utilization shoreline,developed industrial utilization shoreline,developed livelihood shoreline,and developed ecological shoreline),and studied the functional localization of development suitability and development thresholds.The results show that protected area and reserved area are unsuitable for development and construction,the thresholds of controlled utilization and developed utilization shorelines are 60%~70%and 70%~85%respectively,and with development potential of 40%~50%and 90%~100%.The research results can provide scientific basis for the development,refined management and the sustainable development and utilization of the river shoreline.
