基于水土保持的宜宾市土地利用空间重组

    Spatial re-distribution of land use based on water and soil conservation in Yibin City

    • 摘要: 该文在GIS技术支持下分析了宜宾市水土流失与土地利用间的相互关系,以期为宜宾市土地利用空间重组提供战略思路。结果表明,水土流失多发生在自然因素与人类活动强度吻合较好的地方。因此,土地利用空间重组的目标即是通过土地利用的调整,规避生态敏感区或以能够逆向调节区域生态敏感性的方式利用土地,以有效的减缓水土流失。该文还提出了宜宾市土地利用空间重组的基本模式,即“结构调整+空间集聚”。

       

      Abstract: In order to enlighten land re-distribution in Yibin City, between land use and soil and water loss in Yibin City were explored with the support of GIS technology. Results show soil and water loss is more ready to happen that the stronger human activities are in the ecologically sensitive areas, which are more susceptible to be eroded in terms of the situation of their natural environment. So the goal of land re-distribution is to avoid locating strong human activities in the ecologically sensitive areas or to use land in these areas in a way which can withstand the sensitivity. The paper also find that the primary model of spatial re-distribution of land use is to adjust the land use structure and use land in a more efficient way.
