GIS和RS支持下宁夏水稻低温冷害监测预警
Monitoring and Early Warning of Paddy Rice Low Temperature Cold Damage in Ningxia with the Support of GIS and RS
摘要
Abstract
The low temperature cold damage of paddy rice is the major agricultural meteorological disaster in Ningxia. The real-time monitoring and early warning of low temperature cold damage are very important to develop the advantages, avoid the disadvantages and reduce the disaster losses. Based on the prior researches on the low temperature cold damage indexes of paddy rice, we improved the small grid reckoning method of temperature and the reckoning precision with the support of GIS. By using the multitemporal remote sensing data, the paddy rice planting zone was picked. The calculation results of low temperature cold damage monitoring indexes were combined with the paddy rice planting zone, which judged the grade distribution and zone of low temperature cold damage in real time. Meanwhile, the low temperature cold damage of paddy rice was done the early warning, and the automatic monitoring early warning system was developed by using the weather forecast data. This method and system were applied to the business works, and the monitoring and early warning products of paddy rice low temperature cold damage business were made. The monitoring results basically corresponded with the actual situation, and the better monitoring service effect was gained.关键词
