摘要
漓江水资源"丰-枯"变化对漓江水域景观美景度产生重要影响。从漓江水域景观美景度出发,运用层次分析法(AHP法)进行景观美景度评价,结果表明:(1)水体、河岸带和游客是水域景观美景度评价的主要内容。水质(0.1265)和水相(0.0714)是关系水体美感度的最重要指标。而植被(0.1423)和驳岸(0.0791)是河岸带的两个重要组成部分,其中,植物长势(0.1423)和驳岸的自然程度(0.0791)分别是其最重要因子。(2)丰水期、过渡期和枯水期的综合评价值分别为2.81、4.46和3.59。过渡期景观美景度处于极佳等级,而丰水期和枯水期处于优美等级,枯水期综合评价值明显高于丰水期。(3)为构建优美的漓江山水景观,应尽量保持河流的自然风格,减少人工景观和人为活动对自然景观的影响。柔化驳岸与水体的交界面,构建自然式驳岸。根据水位要求,分级栽植植被,形成层次丰富的植物景观。
The changes of Lijiang River water resource in its wet season and dry season have a significant impact on the beauty of waters landscape. Starting with the beauty of Lijiang River waters landscape, use is made of AHP to assess beauty of waters landscape. The result shows： Firstly, waters, riparian zone and tourists represent the major assessment contents of the beauty of waters landscape; water quality （0.1265） and hydrofacies （0.0714）represent the key indexes for beauty of Waters; vegetation （0.1423）-and revetment （0.123） constitute the two important parts of riparian zone. Secondly, integrated assessment values obtained in wet season, transition period and dry season are respectively 2.81, 4.46 and 3.59, indicating exceptional beauty of waters landscape during transition period with integrated assessment values obtained in dry season obviously well above those obtained in wet season. Lastly, construction ot the beautiful Lijiang River landscape calls for maintenance of the river natural styles, reduction of influence of artificial landscap.e and human activities on natural landscape, softening of revetment and water interface and construction of natural revetment. Efforts need to be made on graded cultivation of vegetation based on water level, with a view to forming diversified layers of vegetation landscapes.
