Based on the theory of location quotient,this paper made a quantitative analysis of the dominant agriculture in the agricultural districts and counties of Tianjin. According to the analysis,it made a qualitative analysis of the factors. Finally,it determined the dominant agriculture of each agricultural district and county of Tianjin.展开更多

文摘At present,developing the dominant agriculture plays an essential role in promoting the agricultural modernization of Tianjin. Based on the theory of location quotient,this paper made a quantitative analysis of the dominant agriculture in the agricultural districts and counties of Tianjin. According to the analysis,it made a qualitative analysis of the factors. Finally,it determined the dominant agriculture of each agricultural district and county of Tianjin.

文摘As the basic administrative unit of China,counties have grown rapidly in recent years in the context of rapid urbanization,especially for counties located in mountainous areas.The drastic changes in land in mountainous areas can easily cause irreversible damage to the sensitive ecological environment.Through the dual-objective suitability zoning of ecological and construction balance,regional sustainable land use patterns can be realized.In this study,Hantai District in Southern Shaanxi province,China,was chosen as the research area aiming at creating a balance between ecological supply and the development of construction in spatial planning.A dual-objective process evaluation system for ecological protection and construction development was proposed with 15 resistance factors selected from three attributes:natural ecology,economic society,and policy.The minimum resistance surface discrimination methods for ecological land and construction development land were proposed based on vertical space superposition and horizontal minimum cumulative resistance models.Finally,the land in Hantai District was divided into four development grades from the optimal angle of dual goals,i.e.,the construction core zone being 134.56 km^(2),the suitable construction zone 115.77 km2,the ecological buffer zone 153.74 km^(2),and the ecological control zone 151.93 km^(2),using the method combining resistance difference and threshold division.In addition,the development direction of each town under jurisdiction was identified.This study compensates for the deficiency of traditional methods that evaluate land only from a single vertical or horizontal process.
文摘目的通过对汕头市、区二级疾控中心的人力资源相关数据进行比较分析,了解疾控中心人力资源配置现状,为汕头市各级疾控中心人才资源配置及专业队伍建设提供参考。方法通过标准表格收集汕头市2022年12月—2023年5月1个市级和7个区(县)疾控中心的人力资源数据,采用描述性方法对疾控中心人员的性别、年龄、职称、学历学位和专业背景等情况进行分析。使用Excel和GraphP ad Prism软件进行数据统计及差异比较分析。结果汕头市、区二级疾控中心人员性别构成较均衡,男女比例分别为48.1%和51.9%,差异无统计学意义(χ^(2)=0.66,P=0.42)。市级疾控中心35岁以下人员占比较区(县)级CDC高(分别为35.5%和18.9%),二级疾控中心人员年龄构成差异有统计学意义(χ^(2)=16.68,P<0.001)。市级疾控中心人员学历以本科、硕士为主,占77.6%;但区(县)疾控中心职工学历严重失衡,以本科、大专为主,硕士人员比例仅为1.7%,二者学历构成差异有统计学意义(χ^(2)=87.43,P<0.001);市级疾控中心人员职称集中在中级、高级职称,占比为55.2%,无职称人员占比为10.3%;区(县)疾控中心人员职称主要集中在中、初级,占比为71.4%,无职称人员占比为21.0%,二者专业技术职称构成差异有统计学意义(χ^(2)=33.99,P<0.001);二级疾控中心职工专业背景均以卫生专业为主(77.4%),二者专业背景构成差异无统计学意义(χ^(2)=1.35,P=0.24)。结论汕头市、区二级疾控中心在编人员总量不足,其中区(县)疾控中心职工总体学历偏低,人才配置不平衡,高层次人才总体缺乏;当地政府应当重视疾控人才队伍建设,提高已有专业人员的专业水平,积极引进高层次人才,切实做好本市各级疾控中心的人力资源规划。
