【摘要】：綜合考慮全省地形地貌、農(nóng)業(yè)氣候、土壤類型等自然屬性信息,以及灌溉和雨養(yǎng)農(nóng)業(yè)區(qū)、糧食主產(chǎn)區(qū)、易旱區(qū)等空間分布特點(diǎn),提出了基于多源信息的土壤墑情站網(wǎng)規(guī)劃布設(shè)原則和方法,運(yùn)用Arc GIS技術(shù)實(shí)現(xiàn)空間信息的疊加、提取和融合;并在已有站網(wǎng)基礎(chǔ)上對研究區(qū)土壤墑情監(jiān)測站網(wǎng)進(jìn)行了規(guī)劃布局。全省共規(guī)劃土壤墑情監(jiān)測站392個,其中已有墑情站71個,新增墑情站321個;規(guī)劃墑情站平均代表面積399.49km2,站網(wǎng)密度每縣3.92個。該方法可為抗旱管理部門墑情站網(wǎng)規(guī)劃建設(shè)提供技術(shù)支持和參考。
[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.
