Research Of Town Green Space System Planning Based On Ecological Infrastructure Theory

The green space system planning of towns is an important topic in the green space systemplanning, during the urban expansion of China,the problems like the deterioration of environment,shortage of resources, imbalance of ecological all force us to change the attitudes to environment, andplan green system planning of towns from the perspective of ecological infrastructure.By the help of ecological sensitivity assessment method and landscape ecological security theory,the ecological sensitivity factors of land use type, regional exploitation intensity and distance from theenvironmental sensitive area and so on were selected to evaluate the ecological sensitive degree andits spatial distribution situation comprehensively under the survey of ecological land use status inFuhai town, connected with landscape pattern index. The results showed that the ecological land use athigh, medium, low sensitivity level occupied7.16%,27.29%and30.46%of the total area respectivelyand the rest of35.09%was not ecologically sensitive. According to the data above, this paperclassified three types of ecological land use such as core protection zone, limited development zoneand suitable development zone from ecological security aspect.On the basis of ecological land use classification,this paper proposed that"one core, two areas,three corridors, multipoint"is the overall layout of Fuhai town green space system planning, and,thethree levels of the green space system are being planned:the macro level, the meso level and the microlevel.Firstly,starting from the landscape security pattern, the macro level planning proposed fourlandscape security pattern construction contents of Fuhai town: biological processes, recreationculture, disaster prevention and river system.Secondly, the meso level planning determine differenttypes of green space classification and make it logic to plan the green space of Fuhai town. Lastly, bythe designing for the detailed planning, the shelter forest planning of the wetland and rivers are beplanned.This paper also presented the management countermeasure of different ecological land usetypes in order to supply planning basis and construction strategy for reasonable exploitation ofecological land use in Fuhai town.
