上海市生态用地的服务功能评估及发展策略

Research on the Method of Style Planning for New Area under the Perspective of Innovation Implementation

以“标准林地”生态服务当量为参照,运用土地使用现状调查、遥感信息判读等数据,结合千年生态系统服务功能框架,通过GIS平台,对上海市生态用地的服务功能进行了相对量化评估.评价结果显示:上海市陆域范围内各类生态用地提供的生态服务功能量相当于332 419 hm2标准林地所提供的生态服务功能量,总量相当于覆盖了48.6％面积的标准林地.从所有的生态服务功能价值来看,湿地所占的比重最大,其次为林地、绿地、水田、旱地、园地、草地、荒地.从空间分布特征来看,人均生态服务量布局上由市中心向郊区呈梯级增加,地均生态服务量则呈分度特征.与标准林地相比,水田、旱地、园地、草地、荒地生态服务功能有较大的提升潜力.最后,提出了生态建设策略建议.

Taking ‘standard forest land’ ecological service equivalent as reference,using the data of land use,land cover status survey,remote sensing information interpretation and other data,combined with the Millennium ecosystem service function framework,through GIS platform to assess ecological service value of ecological space of shanghai.The assessment results are as follows:the ecoservice function amounts of shanghai Ecological space is 332 419 hm2 standard forest equivalents which correspond to cover 48.6％ of standard forest in area.Among the ecological space types,wetland has the largest proportion of service functions followed by woodland,paddy field,dry land,green land,orchard,grassland,wasteland.From the spatial distribution characteristics,the ecological service quantity per capita increases from the urban center to the suburban area,and the average ecological service quantity show the characteristic of division.Compared with the standard forest land,paddy field,dry land,orchard,grassland and wasteland still have potential to improve and rise ecological service functions.Finally,the ecological construction strategy recommendations are put forward.
