摘 要

城市湿地公园具有涵养水源,防洪抗旱,沉积营养物质,调节小气候,维持生物多样性等功能。但由于人类的不合理规划和过度利用使得湿地现状岌岌可危。为了保护和利用城市湿地公园,提出并实施有效科学的方法途径,对其进行景观生态评价也成为重要途径。

本文以张家港暨阳湖湿地公园为研究对象,运用景观生态学等理论对其景观类型特征、景观格局指数、景观生态要素展开定量分析,同时还要结合国内外对该课题相关的文献研究进行分析。最终得出该湿地公园的景观生态现状,可以更好地去制定有效保护和合理开发利用的方法途径。本文主要得到结果如下:

1)暨阳湖湿地公园总占地175.57hm2,湿地面积108.07hm2。栽种植物399种,鸟类73种,水环境质量达国家II类标准。经计算CEI处于0.75—0.85范围,景观质量较好,但与优良景观仍存在一定差异,可以多项措施进一步提高。

2)采用层次分析法,构建景观生态指标评价体系。包括生态、生活、美学三方面指标层,21个指标要素,对其进行权重计算,求得三个矩阵CR值均小于0.1,具有满意的一致性,不需要调整。通过问卷调查获得各层指标重要性,生态价值指标中水环境质量最重要,生活价值指标中垃圾污水处理设施最重要,美学价值中破碎化指数最重要。表明了人们对于水质量以及废物处理回收的重视。

The ecological evaluation of Jiyang Lake wetland park landscape in Zhangjiagang

ABSTRACT

Urban Wetland Park has water conservation, flood control and drought, deposition of nutrients, regulate microclimate, maintenance of biological diversity and other functions. However, due to human over-exploitation and irrational planning making the precarious status of wetlands. For the protection and utilization of urban wetland park, to propose and implement effective scientific method approach, its landscape ecological evaluation has become an important way.

Taking zhangjiagang jiyang lake wetland park as the research object, by using the theory of landscape ecology and other characteristics of the landscape types, landscape pattern index, a quantitative analysis of the factors of landscape ecology. Also combining domestic and foreign related literature research analysis of the subject. Finally results of the ecological status of the landscape of the Park may be better ways to devise a method effective protection and rational development and utilization. In this paper the results obtained are as follows.

1) Jiyang lake wetland park covers an area of 175.57 hm2, wetland area of 108.07 hm2. 399 kinds of plant growth, 73 species of birds, water environmental quality of national class II standard. By calculating the CEI in the range of 0.75-0.85, landscape quality is better, but there still exists certain differences, and good landscape can be a number of measures to further improve.

2) Use the AHP, to construct landscape ecological index evaluation system. Three aspects including ecology, life, aesthetic index layer, 21 indicator elements, the calculation of weight for CR and the three matrices are less than 0.1, with satisfactory consistency, do not need to adjust. Through the questionnaire survey to obtain the layers of the importance, ecological value index, water environmental quality is the most important life sewage treatment facilities in the most important value index, fragmentation index, the most important aesthetic value. Shows that the people’s attention for water quality and waste recycling.

1.1研究背景

湿地是陆地生态系统与水生生态系统之间的过渡带,是地球巨大而宝贵的资源库。由于其多种很多样的功能,而被称为“地球之肾”。由此可见其重要性。

城市作为人类文化的产物,随着人类社会经济活动的加强而日益增多。城市湿地作为城市的后花园,其重要性也日益凸显。然而随着人类活动的加强,湿地也在被不合理的开发利用破坏,最终使得湿地的各种环境因素发生了变化。而且同时由于城市化现象,湿地的面积也大大减少,而且湿地的污染情况也不容乐观。所以近年来对于湿地的保护、恢复和建设项目得到非常大的发展。而对于城市湿地的评价也相应的提上了台面。
