GIS支持下的青石山小流域农业生态信息系统(QWAEIS)及其应用研究

Qingshishan watershed agro-ecology information system and its application with the support of Geographic Information System(GIS).

应用地理信息系统 (GIS) ,建立了青石山小流域农业生态信息系统 (QWAEIS) ,该系统综合了土壤、土地利用、水资源及地形地貌等空间信息和气候、人口、农业生产等基本信息 .该系统能对小流域农业生态信息进行有效地分析和管理 ,应用此系统 ,进行了小流域的土地适宜性评价 ,获得土地适宜性评价结果 ,为小流域规划提供了空间定位信息 .

Geographic Information System(GIS)is applied to establish Qingshishan Watershed Agro Ecology Information System(QWAEIS),QWAEIS integrates spatial information such as land use,soil,water and topography with basic information such as population,climate and agricultural production.The watershed agro ecology information was effectively analyzed and managed by QWAEIS,land suitable classes were evaluated by QWAEIS and the land evaluation result are given,QWAEIS also can support watershed planning with its spatial information.
