摘要
农作物种植结构是掌握灌区农作物种植面积与分布、摸清作物需水量的基础资料。充分发挥3S技术优势,以高分辨遥感影像为数据源、GPS技术为外业调绘主要工具、GIS软件为遥感数据解译和数据内业处理平台,进行宁夏引黄灌区农作物种植结构调查。调查结果表明:2009年宁夏引黄灌区农作物种植总面积为4 967.58 km2,以粮食作物为主,小麦、玉米和水稻为主要作物。
Crop planting structure is the basic data to know the area and distribution of irrigation region and find out crop water requirement. Due to the advantages of 3S techniques,high resolution remote sensing data was used as survey data,GPS was used for field survey and GIS was used for image interpretation and data processing in the survey of crop planting structure of Ningxia Yellow River irrigation region. Results show that the total planting area of crops is 4967. 58 km^2 in Ningxia Yellow River irrigation region. Wheat,corn and rice are the main crops.
