Layout And Plant Diversity Of The Green Open Space In Foshan City

The city is the symbol of modern civilization. In recent years, with the human mass without restraint does not conform to the laws of nature urbanization development, destroyed the harmonious development between human and nature, make the ecological environment problems become human social facing the most serious crisis and the biggest obstacle to urban sustainable development. Urban green space as a city, part of the natural ecological system in improving the environmental quality, and beautify the landscape, maintaining ecological balance, promote urban aspects of urban sustainable development plays an extremely important role. As a improvement of the ecological environment function of urban green space system, it is undoubtedly the effective ways to solve this problem, and the reasonable layout of urban green system can make more effective use its ecological functions. Meanwhile, urban plant as urban green space system is the important constituent, therefore, the study of urban plant diversity also has a special meaning, how to use existing native plants for urban green space system services and protecting city plant diversity become the hottest urban forest construction urgent problems.This paper in Foshan city urban green space system layout and afforestation plant biodiversity as the research object, in full investigation Foshan city green land based on the present situation of the existing urban green space, according to different types of green features and classification individually analyzed and appraised. Mainly including public green status and accessibility analysis, greening coverage area and its street trees are analyzed, and the residential green and green advantages and disadvantages analysis, unit production from the rate is affiliated green indicators analyzed; Landscape ecological principles and methods Fragstats Arcview and, with the help of Foshan city software, green landscape index calculation thus analysis of urban green space overall landscape pattern, the different functional areas of the landscape pattern and city green coverage the landscape pattern; By using systems to Foshan city green space system layout analysis. At the same time through extensive reading literature work and field investigation of Foshan city landscape plant diversity, aiming at analysis evaluation, Foshan green land evaluation, planning and construction layout, protecting biodiversity provides scientific basis and theoretical basis. The results of the study to improve the urban environment, the green space system planning and rational layout structure, urban plant diversity protection has certain theoretical and practical value. In order to urban green space system planning for the future construction to provide the theory basis and the beneficial reference.This paper mainly conclusions as follows:1. The green landscape analysis results:Foshan city by 0.2-10 city hm2 medium green cover plaques covering area accounts for 44.76% mainly. Green coverage area< 0.01 hm2 green patches of the green in the finished the area covered by a green cover 4.27%, but the total number 79.88% patch purpose; 0.01～0.2 hm2 small green green coverage area accounts for the number of 21.38%, its plaques 18.18%;> 10 hm2 large green coverage area accounts for 29.59%, patches of 0.04% number. Foshan city afforestation landscape mainly by the medium-large green control, but scattered small green quantity, caused the landscape fragmentation degree is higher.2. Foshan city urban green space system layout belong to "green ring+green gallery +green wedge+plaques" form "2-ring" city band mesh green space layout mode. Green space system layout structure "2-ring" respectively are:(1) means along Foshan first ring width of both sides express line of 50m set for greening; (2) along the river; inner sides greening set In this paper, the green gallery within the range of research refers to Foshan city road greening the seven longitudinal seven, and is building green way nets; Green wedge mainly by the distribution in Foshan city of large green border, plaques are scattered through out the Foshan by the small and medium green space composition.3. In Foshan urban green space in the frequency of the 10 highest respectively, Taiwan grass, nine white orchid, sweet, mango, and fine YeRong fu, urticaceae, the short spike fishplate kwai, mountain GaoShanRong, nails and its frequency 52.12%, the order is 19.64%,13.83%11.27%,9.79%,9.189%,7.21%,6.96%7.44%, and 5.01%, combined with relative frequency for 60.22%. In the investigation of five kinds of urban green space landscape plant abundance, the sequence of public green space> residential area for:> unit affiliated green green forest> protective greenbelt landscape.
