【摘要】：灞河,古称滋水,地处陕西省东南部,是黄河支流渭河的支流。灞河,昔日“八水绕长安”美景中的八水之一,也是当今西安市生态建设的重要组成部分,更是西安市重要的水源地之一。然而,随着城市化进程的快速发展,灞河的水源受到污染,生境系统遭到破坏,湿地逐渐被高楼建筑所代替,湿地面积也在逐渐缩小,严重影响了灞桥区的整体发展。值得欣喜的是,西安市委十二届八次全会审议通过的《西安市国民经济和社会发展第十三个五年规划纲要》提出了持续推进生态文明建设的总目标,为灞桥区的发展提供了新的契机,灞桥区将加大灞河流域的治理力度,为西安市的生态文明建设作出积极的、应有的贡献。本文对灞河沿线的现状进行分析,提出将湿地生境恢复运用到灞河沿线湿地景观设计中。全文共分为五个部分。第一部分是概述灞桥区这个整体背景,以及灞桥区的现状;第二部分是针对湿地以及湿地公园的概念进行论述;第三部分是灞河沿线湿地景观带的综述,分别从灞河存在的问题、灞桥区的区位优势对灞河沿线景观带的影响这两个方面来阐述这一部分;第四部分是针对灞河沿线这一现状提出湿地生境恢复这个研究主题,就灞河这个区域,分析生境破坏的原因,以及如何进行生境恢复;第五部分是实践部分,对灞河沿线湿地景观带的规划,在规划中运用自己的研究成果,探索出恢复湿地生境的诸多措施和办法。湿地生境恢复主要是水文和土壤,基底缺水造成物种的栖息地破坏,继而影响湿地的生境系统,湿地面积逐渐消失。提高水位,建设生态驳岸可以进一步实现湿地的生态恢复,从而建设绿色生态灞桥。
[Abstract]:Bahe, the ancient name Zishui, is located in the southeast of Shaanxi Province, is the tributary of the Yellow River Weihe River.Bahe, one of the eight rivers in the beautiful scenery of "eight rivers around Chang'an", is also an important part of ecological construction in Xi'an and one of the important water sources in Xi'an.However, with the rapid development of urbanization, the water source of Bahe River is polluted, the habitat system is destroyed, the wetland is gradually replaced by high-rise buildings, and the wetland area is gradually shrinking, which seriously affects the overall development of Baqiao District.It is gratifying to note that the outline of the 13th Five-Year Plan for the National Economic and Social Development of Xi'an, which was deliberated and adopted by the eighth Plenary session of the twelfth session of the Xi'an Municipal Party Committee, set out the overall goal of continuously promoting the construction of ecological civilization.It provides a new opportunity for the development of Baqiao District. Baqiao District will strengthen the management of Bahe River Basin and make positive and due contributions to the construction of ecological civilization in Xi'an City.This paper analyzes the present situation of Bahe River, and puts forward the application of wetland habitat restoration to the wetland landscape design along the Bahe River.The full text is divided into five parts.The first part is an overview of the overall background of Baqiao District, as well as the current situation of Baqiao District; the second part is to discuss the concept of wetland and wetland park; the third part is a summary of the wetland landscape along the Bahe River.From the aspects of the problems existing in Bahe River and the influence of the regional advantages of Baqiao District on the landscape belt along the Bahe River, the fourth part is to put forward the research theme of wetland habitat restoration in view of the current situation along the Bahe River.In the area of Bahe River, the causes of habitat destruction and how to restore the habitat are analyzed. The fifth part is the practice part, in which the planning of wetland landscape along the Bahe River is made use of its own research results.To explore many measures and methods to restore wetland habitat.The restoration of wetland habitat is mainly hydrology and soil. The habitat of the species is destroyed by water shortage in the basement, and then the habitat system of the wetland is affected, and the wetland area is gradually disappeared.Raising water level and constructing ecological barge can further realize ecological restoration of wetland and thus construct green ecological Baqiao.
