城市滨水区生态现状及修复

城市滨水区是城市绿色生态的重要组成部分。它在提供水源、绿地、改善环境的同时,还具有开放旅游娱乐、交通运输、文化教育等众多生态功能,对城市的发展具有着重要的生态、经济和社会价值。而随着社会的飞速发展、城市化进程的加快,人类对城市滨水区盲目地、不科学地建设引发了一系列关系到滨水生态破坏的严重问题。在环境越来越受到关注的现今,这一切逐渐引起了人们的高度重视。从城市滨水区景观规划不合理、防洪工程存隐患、污染物排放加剧、生物多样性减少等方面分析了滨水区的生态现状。并在此基础上从生态学的角度提出了植物修复、重构系统食物链、重建缓冲带及滨水绿化、实施生态护岸、增加物种重建群落等一些恢复滨水生态的途径。     

Square Design of Mountain Cities: A Case Study of Shiyan Broadcasting Media Center Square

City squares are an important part of urban public spaces and play an important role in improving the quality of urban landscapes. For mountain cities, city squares with mountainous characteristics formed by its special geographical environment, which have more identifiability and uniqueness than that in plain cities, have greater influence on the promotion of city image. Their unique regional cultural characteristics and local customs and practices have shaped the totally different temperament of mountain cities. Based on the dialectical relationship between the square, the landscape and the culture, this paper took Shiyan Broadcasting Media Center Square for example to explore the ideas of landscape design in mountain cities.

Open Park Transformation and Upgrading Means of Comprehensive Park: A Case Study of Xuzhou Quanshan Forest Park

The transformation and upgrading of comprehensive park can not be only limited to the adjustment for structure, function and landscape facility of comprehensive park itself, which shall be carried out as a whole. Viewing from the macroscopic perspective of city, comprehensive park is an important constituent part of urban green space system, and its transformation is an integral part of overall perfection and development of urban green space system. Park is an organic integrity comprising many elements. The transformation of comprehensive park shall be carried out as a whole and handled by using the methods of "from top to bottom" and "from bottom to top", thus adjusting the relationship between park and city and within park on the whole. This research takes the open park transformation and upgrading of Xuzhou Quanshan Forest Park as an example to introduce the key points of open park transformation from such aspects as of entrance space, overall space structure, service function expansion and spatial form optimization in expectation of having a certain reference value.

Evolution and Simulation of Spatial-temporal Heterogeneities in Ecological Background Quality of Changsha City

By GIS and ENVI,TM/ETM remote sensing images of five districts(Yuelu District,Furong District,Yuhua District,Tianxin District and Kaifu District) in Changsha City center in 2005,2010 and 2015 were interpreted.Moreover,distribution chart for ecological background factors in 2020 was simulated by using CA-Markov module in IDRISI.Using principal component analysis,evaluation model for ecological background quality of the city was established.Via circle analysi s,GS+semi variance function analysis,hot spot area analysis and grey correlation analysis,integrated analysis and evaluation on spatial heterogeneity evolution of ecological background quality in research region were conducted.Results showed that firstly Changsha overall has formed ecological pattern of landscape island city,but ecological background started to show the evolution trend of high heterogeneity and fragmentation under the construction land expansion,and ecological background quality of the city declined from 0.300,6 to 0.257,1 during 2005-2020.Secondly,ecological background quality of Changsha City had typical circle and axial gradient structure,and "eco tone" had the most violent evolution.Thirdly,spatial structure of ecological background quality had region,time and direction heterogeneities,and spatial heterogeneity of region was the most important.Fourthly,hot spot area distribution of ecological background quality evolution showed the "frog jump" trend of gathering in marginal zone and diffusing to peripheral zone.Fifthly,in driving factors of ecological background quality,industrialization rate had the highest grey correlation degree(0.842,1),and grey absolute correlation degree between ecological background quality in Yuelu District and industrialization rate was the highest(0.603,1).
