固原市绿地生态网络构建研究

Study on construction of ecological network in Guyuan City

固原市地处黄土高原半干旱地区,土质松软且降水时间集中,水土流失严重,文章以构建绿地生态网络来改善其生态大环境,增加绿地生态网络循环的完整性。通过卫星地图对固原市原有的绿地斑块以及水系分布进行分析,以其绿地和水体的条带状分布为构建依据,选取具有生态保护价值的地块以廊道的形式进行连接,构建以保护森林生态、涵养水源、保护历史遗迹为最终目的的绿地生态网络,并在此基础上对生态网络的植物配置进行大致规划,以期为其他环境相似的地区进行相关建设提供一定的参考和借鉴作用。

Guyuan city is located in the semi-arid region of the loess plateau, where the soil is soft and the time for rainfall is relatively concentrated, which leads to a serious soil erosion. This paper discusses the strategy that the construction of green ecological network is used to improve its ecological environment and the integrity of the green ecological network cycle, analyzes the original patches of green land and the distribution of water system in Guyuan City through satellite map, and builds the green land ecological network based on the eventual purpose of protecting the forest ecology, water resource conservation and protecting historical sites, by taking its green land and banding distribution of water body as construction basis and connecting the ecological protection valuable land parcel through selection by the form of corridor. On this basis, the plant disposition of ecological network is generally planned in order to provide a reference and help for the relative construction in other areas of similar environment.
