Evaluation And Optimization Of Recovery Resources On Agricultural Drought In Hunan

Because drought with characteristics of a wide range, long duration, severelosses, it becomes one of the largest natural disasters causing agricultural losses. Asa major agricultural province, Hunan Province is not a agricultural powerfulprovince. But agriculture is one of the important economic pillars. Due to the mutualinfluence and role between climate and terrain features in Hunan Province, makingHunan province has also become agricultural drought areas easily and frequently.Therefore, this article takes Hunan Province with a resource conditions as a startingpoint, then through researching and analyzing the actual situation in Hunan Provinceand optimizing resources, and finally it improves the resistance and resilience ofHunan agricultural drought under the base of resources levels, which reducesagricultural drought losses and disaster preparedness has important practicalsignificance.Resources not only affect the strength of the agricultural drought, but also playa significant role on agricultural drought recovery. Therefore optimizing resources isalso improving the agricultural drought resistance and resilience. The paper studiesthe restorative resources, which are available to be restored and updated, oroptimized by human factors of agricultural resources in the process of agriculturaldrought. Firstly, it overviews the specific situation of Hunan Agricultural drought,and according to the distribution as well as the degree of intensity of drought, itdivides Hunan Province into eastern, southern, western and northern and in the amidof Hunan in five regions, and takes restorative resources as the main research factorsin this situation five region, it makes collate statistics and correlation analysis ofrestorative resources in these five areas. And then it builds an AHP evaluation modelon a resource of Hunan Agricultural Drought restorative resources to determine therelevant indicators and related data obtained through questionnaires and scores.More, through the appropriate formula to calculate the data of the recovery resourceslevel for agricultural drought in these five areas, and it come out the results of thedata of five regional resource recovery level. Finally, according to the level situationof each recovery resources, it put forwards to some reasonable and feasibleoptimization measures to improve the level of recovery resource in each region,thereby improving drought resistance and resilience of agriculture in all regions as to improve the resistance and resilience abilities of agricultural drought in the wholeHunan Province.
