Research on Urban Agricultural Scientific Development Path of the Construction of Central Economic Region

The significance of developing characteristic agriculture in Central Economic Zone was elaborated from four aspects of three modernizations coordinated development,guaranteeing city supply of agricultural products,creating more jobs for farmers,making agriculture more significant. The existing problems in urban agriculture development were analyzed,such as understanding deviation,extensive development,market confusion,short industrial chain,low degree of specialization,harsh environment. Several corresponding countermeasures were put forward,including giving full play to the role of government's macro-control; perfecting compensation mechanism of urban agriculture,developing characteristic agriculture,promoting deep processing of agricultural products; advancing scientific innovation,improving production efficiency;operating sustainable ecological agricultural development road; relying on traffic advantage,promoting industrialization operation and urban agricultural logistics development.

STUDY ON TYPHOON DISASTER LOSS AND RISK PREDICTION AND BENEFIT ASSESSMENT OF DISASTER PREVENTION AND MITIGATION

Based on the meteorological monitoring data of Typhoon Nesat and Haitang in Fujian Province in 2017, the data of the typhoon disaster situation and third-party evaluation of typhoon disaster prevention and mitigation benefit were investigated. By using the mean value anomaly estimation method in the similarity analysis method, it is estimated that typhoon Nesat and Haitang will cause direct economic losses of 0.8 ～ 1.8 billion yuan, and the typhoon disaster risk index evaluation model is used. The disaster risk pre-assessment of Typhoon Nesat and Haitang is carried out. The results of the study and analysis show that the pre-assessment results of Typhoon Nesat and Haitang are basically consistent with the actual disaster situation. The disaster loss was reduced to the minimum. According to the third party evaluation and investigation, it was concluded that the contribution rate of reducing economic benefits was 75% in Fujian Province for preventing and landing double typhoons Nesat and Haitang. Mainly reflected in the ship return to the port to avoid the wind, geological hazards prone to the site construction and cage culture danger removal reinforcement and other links; The contribution rate of reducing casualties is 86, mainly reflected in fishermen disembarkation and personnel transfer to safety emergency shelter and other links. The benefit of this double typhoon disaster prevention and mitigation in Fujian Province is about 0.6 billion yuan to reduce the direct economic loss. According to the investigation, the overall satisfaction of the double typhoon meteorological service is 91.0 points. Typhoon early warning information service convenience satisfaction is 91.4 points, early warning information accuracy satisfaction is 87.2 points, government departments strong anti-Taiwan disaster reduction organization, linkage departments participate in disaster prevention and mitigation high. However, there is a gap between public awareness and participation in typhoon disasters.
