Research on the Socialization of Grassroots Meteorological Services in Agricultural Supply-side Structural Reform

In 2017, the No. 1 Document of the Central Committee proposed that "it is necessary to further promote agricultural supply-side structural reform, accelerate the cultivation of new kinetic energy for agricultural and rural development, and create a new situation in the construction of agricultural modernization". Under the new normal, Zhejiang s agricultural development shows new characteristics and new trends of speed change, structural optimization, and power conversion, and meteorological services for agriculture have stronger demands, higher requirements, and heavier tasks. The socialization of meteorological services is a new type of system arrangement for the provision of meteorological services, and aims to provide high-quality and efficient meteorological service products for the public and promote the equalization of basic meteorological services in urban and rural areas. In this study, through research on the socialization of grassroots meteorological services in a new situation, a new way of the government to provide public weather services is proposed, and a mechanism of the government to purchase public meteorological services is established;social resources and forces are organized and guided to develop the innovation system and mechanism of public weather services, and social resources are fully mobilized to meet the demand for meteorological services in the process of agricultural supply-side structural reform.

Analysis of Differences between Requirements of Public Meteorological Services from a New Perspective

Based on the survey data of public meteorological services,differences between users' needs for public meteorological services were analyzed by using Maslow's hierarchy of needs and the principle of information availability in behavioral economics. The results show that users' needs for meteorological services follow certain laws,and the public's needs for meteorological information are driven by physiological needs firstly and then by safety needs,while they are driven by upper needs finally. Meanwhile,users' needs for meteorological services have particularity.Under special backgrounds,there are certain differences between users' needs and laws of basic needs,and users' needs are inconsistent with the " ideal needs" of meteorological departments. Studying the laws and particularity of differences between users' needs for meteorological services in detail is conducive to a survey of the public's needs for meteorological services and improvement of meteorological service quality.

Changes in the Beginning Date and Duration of the Four Seasons in Zhejiang Province

Based on data of daily average temperature from 62 national ground observation stations in Zhejiang Province during 1971-2015,the changing trends and spatial distribution of beginning date and duration of the four seasons in Zhejiang Province were analyzed by using the least square method,and significance test was conducted by using correlation coefficient. The results show that according to the changing characteristics of the four seasons in Zhejiang Province,autumn and winter began later,while spring and summer started earlier than before; the duration of summer lengthened,while the duration of winter shortened,and there were great changes in summer and winter but small changes in spring and autumn. Seen from the spatial distribution of beginning date and duration of the four seasons,the correlation in middle and northern Zhejiang was better than that in southern Zhejiang.

Establishment and Application of Comprehensive Evaluation Index of Tourism

According to the actual situation of Zhejiang Province,an objective and quantitative mathematical model used to assess the tourism index of scenic spots was proposed to extend fine and personalized meteorological services to scenic spots and tourists,in which effects of sunshine,wind power,temperature and relative humidity on the comfort of the human body were considered fully,and warning of weather disasters and occurrence of characteristic meteorological landscapes were also considered. The results show that the comprehensive evaluation index model of tourism has full functions of assessment,has guiding significance to the travel of travel enthusiasts and can provide reference for tourism management.
