【摘要】:综合考虑全省地形地貌、农业气候、土壤类型等自然属性信息,以及灌溉和雨养农业区、粮食主产区、易旱区等空间分布特点,提出了基于多源信息的土壤墒情站网规划布设原则和方法,运用Arc GIS技术实现空间信息的叠加、提取和融合;并在已有站网基础上对研究区土壤墒情监测站网进行了规划布局。全省共规划土壤墒情监测站392个,其中已有墒情站71个,新增墒情站321个;规划墒情站平均代表面积399.49km2,站网密度每县3.92个。该方法可为抗旱管理部门墒情站网规划建设提供技术支持和参考。
[Abstract]:Considering the natural attribute information of the whole province, such as topography, agricultural climate, soil type and so on, as well as the spatial distribution characteristics of irrigated and rain-fed agricultural areas, main grain producing areas, drought-prone areas, etc. The principle and method of layout of soil moisture station network based on multi-source information are put forward, and Arc GIS technology is used to realize the superposition, extraction and fusion of spatial information. Based on the existing station network, the planning layout of soil moisture monitoring station network in the research area was carried out. There were 392 soil moisture monitoring stations planned in the province, among which 71 were soil moisture stations and 321 were new soil moisture stations. The average representative area of the soil moisture station is 399.49km2, and the network density of the station is 3.92 per county. This method can provide technical support and reference for the planning and construction of the soil moisture station network in the drought relief management department.
