汶川地震粮食受损遥感快速估算与分析
|
摘要
综合利用灾前IRS P6 Liss-4高分辨率数据与灾后的航空影像,估算粮食受损面积,并利用同期农业气象数据估算了不同受灾区域粮食作物单产水平,最终估算得出震区粮食作物受损产量。监测结果表明:地震造成的12个重灾县市冬小麦直接损失247.1hm2,产量约为1013778kg,直接影响不大。但受灾地区冬小麦总产量超过22万t,而且对秋粮作物的种植和生产造成影响,对中国粮食生产的间接影响不容忽视。
This paper focuses on grain production loss caused by Wenchuan Earthquake.The damage of the cultivated area as well as the yield of winter wheat has been assessed.In order to estimate winter wheat acreage damaged by the earthquake,air-borne CCD images and IRS P6 LISS4 MN data were used.Damaged arable land were extracted by photo interpretation,while winter wheat proportions were collected by ground survey using GVG instrument for plain area or interpreted from airborne images for mountain area.The winter wheat acreage damaged by the earthquake was calculated using winter wheat proportion multiple the area of damaged arable land and statistic at county scale.To estimate wheat yield,reliable agro-meteorological models were selected by taking into account the disperse distribution of winter wheat in mountain area.The results showed that only about 247.1hm2 of winter wheat were damaged in the twelve main producing counties and the production loss of winter wheat was estimated to 1013778kg.As conclusion,the earthquake did not significantly affect the food production of the whole country.Nevertheless,since all farmers were evacuated in mountain area after the disaster,the problems of harvest in that region producing 220000t of winter wheat need to be addressed.
