Abstract


Greenhouse low temperature environment not only make the cucumber Chilling , cucumber downy mildew is likely to cause , to provide meteorological disaster warning and insurance services for greenhouse cucumber production , is important to reduce the impact of low temperature of disasters on greenhouse cucumber production . In this paper, the second generation of energy-saving solar greenhouse in Tianjin as the research object , carry out research -based the WEBGIS greenhouse cucumber cryogenic disaster insurance decision support system , concentrating on the work of the following two aspects : (1) build a low-temperature disaster set loss model . The model is built according to the Baodi holy benevolence Village in greenhouse cucumber data establish the chilling injury index , according to the theory of weather index insurance and Agrometeorological Yield calculated one week time window the cucumber yield loss rate . On the basis of the parameters of the yield loss rate , low-temperature disaster index and average sunshine hours , using multiple linear regression analysis method to construct low-temperature disaster set loss model , this quantitative analysis between of greenhouse cucumber cryogenic disaster yield loss relationship , the model is able to fine determine loss R2 0.7 , which yield volatility and correlation coefficient of cold damage index reached 94.9% . On the basis of the modeling , Dongli District, according to the spring of 2011 , Yonghe Village Greenhouse basic data to predict the relationship between the yield loss caused by the meteorological factors proven this model can well reflect the low-temperature disaster and yield loss . ( 2 ) the development of a the cryogenic disaster insurance decision support system . Based on cryogenic disasters to assess the damage model and the introduction of cucumber downy mildew warning model , low - temperature disaster and downy mildew warning , design of a based on WebGIS greenhouse cucumber meteorological disaster insurance decision support system , the system can be provided according to the meteorological department data , conduct low - temperature disaster and disease early warning , and insuring the user to quantify disaster damage , auxiliary insurance companies to disaster claims work . This article introduced cryogenic disasters Index insurance greenhouse cucumber production , this method can reduce the cost of agricultural insurance , and effectively improve farmers' ability to resist natural disasters risk ; the established cryogenic disasters set loss model , claims for insurance companies to provide scientific and rational basis ; the system for greenhouse cucumber production meteorological disaster warning and insurance services , to provide protection for reducing the risk of agro-meteorological disasters .
