核密度分析，揭示小微湿地的空间分布特征；以条件价值法
(CVM)、影子工程法(SPA)和市场价值法(MVM)等分别计

法对小微湿地涵养水源、调蓄雨洪、固碳、释氧、降尘等生态
价值进行了估算，研究区2019年小微湿地文化生态服务总价

| Characteristics and Value of Urban Wetlands —Taking the Central Area of Nanchang as the Example |

| Abstract: |
| Small and micro wetlands are an important part of urban
landscape. Studying their spatial distribution characteristics and
quantitatively estimating their service value from two aspects of culture
and ecology are of great significance for guiding the improvement of
the urban human settlement environment. Taking the small and micro
wetlands in the central area of Nanchang as the research object, with the
help of ArcGIS platform to carry out the spatial core density analysis of
the small and micro wetlands, the study reveals the spatial distribution
characteristics of the small and micro wetlands; using the conditioned
value method (CVM), shadow engineering method (SPA) and the market
value method (MVM), it measures the cultural and ecological service
values separately. The results show that the uneven spatial distribution
of urban small and micro wetlands, mainly concentrated in parks
and residential areas, is significantly affected by urban planning and
construction; the CVM method is used to measure the water resources
protection, recreation, landscape, and science education of small and
micro wetlands, And the value of cultural services, the ecological values
of small and micro wetlands such as water conservation, rainwater
storage, carbon fixation, oxygen release, and dust reduction have been
estimated through methods such as SPA and MVM. The total value
of cultural and ecological services of small and micro wetlands in the
study area in 2019 was 146.9 million yuan. Compared with other types
of ecosystems, small and micro wetlands have a higher value of cultural
and ecological services per unit area, about 197,400 yuan/(hm2
·a). Based
on above results, countermeasures are proposed to build a sustainable
urban small and micro wetland system, and the study provides new
approaches and references for urban planning and construction. |
