【摘要】 江苏省面积小,耕地少。近年来水质性缺水明显,必须十分珍惜宝贵的耕地土壤资源与灌溉水资源。并且江苏省农区土壤与水体已有污染,苏南地区的土水污染尤为明显和严重,必须进行严密的动态监测进而为土水质量的改善提供合理的建议。传统的水土监测,投入人力,物力大,而且监测周期长,时效性差。遥感和地理信息系统的发展为农区水土质量的监测提供了新的技术手段。本文就是以南京市溧水县为研究区,以中巴卫星为数据源,在实测数据和地理信息系统的辅助下,对农区土水质量宏观动态监测方法的技术体系进行了研究。更多还原

【Abstract】 The area and the farmland in the Jiangsu Province are both small and limited. In resent years,water quality-induced is obvious,so the precious resources of the farmland and irrigated water must be treasured. Moreover,the soil and water in the agricultural region in Jiangsu Province have been polluted,especially in the south of Jiangsu Province,so the rigorous dynamic monitoring has to be done to give reasonable advices for the improvement of the quality of the soil and water in the agricultural region. The tranditional monitoring of the soil and water need too much man power and material ,moreover,the period is so long that its timeliness is also poor.But new technology methods on the monitoring of the quality of the soil and water in the agricultural region were provided by the development of the Remote Sensing (RS) and Geographic Information System(GIS). Therefore the technology system on the macroscopic dynamic monitoring on the quality of the soil and water in the agricultural region was researched using the remote sensing data from the China and Brazil Earth Resource Satellite (CBERS) in this paper under the assistant of GIS and the measured data which takes the Lishui County in Nanjing City as the study.更多还原
