Correlation between Urban Land Change Process and Socioeconomic Development since the 1980s in Jiangsu Province

Studying the process and characteristics of urban land change in different phases of urbanization and different economic development is much important for understanding urban land change and management at a macro level. Taking the example of Jiangsu Province, the present paper studied the correlation between urban land change process and socioeconomic development from 1981 to 2003 on the basis of statistical data. The results showed the following three aspects. First, urban land area has changed periodically and the research duration can be divided into two periods: from 1981 to 1994 and from 1995 to 2003. In each period, the changing trend is the same, i.e. slow at first and then quick. Studying from the comprehensive change status, the characteristic of fluctuant change is significant with three acute change pinnacles in 1988, 1991 and 2002 which were corresponded to turning point years of economic development phases of Jiangsu Province respectively. Second, the synchronization between urban land change and urbanization level change is not strict. With the evolution of urbanization phases, the change pace of urbanization level increased remarkably, but urban land change rate did not increase significantly accordingly. Third, the area of urban land has exponentially increased with the increase of per capita GDP. In different economic development levels classified by per capital GDP, land resource cost for economic development is different, respectively 29.01 hm2, 26.34 hm2, 26.22 hm2, and 11.14 hm2 for the increase of 100 million RMB GDP when the per capita GDP is under 1000, 1000–2000, 2000–5000 and over 5000 RMB.

Examining the Level of Service in the Context of Recreational Carrying Capacity in the Erzurum Urban Forest,Turkey

Urban forests are confronted with high using pressure because of the increasing demand for recreation and accessibility of these settings. For that purpose, defining and managing recreational carrying capacity is considered as significant in ensuring ecological value’s and recreational satisfaction’s continuity. The purpose of this paper is to investigate the carrying capacity of Erzurum Urban Forest with respect to Level of Service (LOS) as a new management technique that focuses on service quality and visitor satisfaction. The data were obtained by self-administered questionnaire conducted with 166 visitors on weekends and holidays during summer season of the year 2014. Data were analyzed by dimensions/indicators of recreational satisfaction and socio-demographic characteristics with intent to identify tolerance range of visitors. The contribution and relative importance of each of the indicators to the overall satisfaction were analyzed by using Ordinal Logistic Model (OLM). The results indicated that the four indicators were at the greatest degree;“distance from picnic spot to toilets” and “quantity of children’s playground facilities” were decease of overall satisfaction while “distance from picnic spot to parking” and “level of shade at picnic spot” had a positive contribution to the overall satisfaction. The outputs from these analyses were used to calculate LOS. It was revealed that the level of service (0.40) in Erzurum Urban Forest was below the moderate level. Planning and managing strategies for optimizing the LOS were developed and discussed by considering these results.

Characteristics of Regional Differentiation of Urbanization Development in Anhui Province

On the basis of connotation of urbanization,by using SPSS factor analysis and cluster analysis,we establish index system of urbanization development level and conduct quantitative analysis on development level of urbanization in 17 prefecture-level city of Anhui Province,in order to find out the differentiation pattern of regional space of urbanization development in Anhui Province based on these.The results show that Anhui's difference of urbanization gradient is prominent.Classification of three clusters shows that the pattern of status quo of urbanization development in Anhui Province is "dual-nucleus" and "two-stretches";classification of five clusters show that the pattern of status quo of urbanization development in Anhui Province is "one-core","one-strip" and "three-region".From five aspects,namely natural geography,transportation location,resources distribution,economic development and administrative system,we analyze the reason and influencing factors of differentiation of urbanization development in the region.The results of three clusters and five clusters show that there is great possibility that "dual-nucleus" changes into "individual-nucleus";"one-core" and "one-strip" may evolve into "one-group".We should foster the urban agglomeration in central Anhui;perfect structure system in the perspective of integration and fostering;strengthen infrastructure construction and regional coordination system;elevate comprehensive competitiveness and guide holistic development of regional economy;promote industrialization process and promote development level of urbanization.

Constructing a Practice-Oriented Education System of Urban-Rural Planning

As China's urbanization accelerates, there is an increasing demand for urban-rural planning at both national and local levels, making it become an independent fi rst-level discipline. Currently in China, the teaching and research system of urban-rural planning is facing some problems like the uneven education level among various universities, improper knowledge system that hardly meets the actual social demands, and insufficient theoretical research. This article argues that, in order to train qualif ied planners capable of satisfying socio-economic development and urbanrural construction, the teaching and research system of urban-rural planning should be practice-oriented and meet social needs. The healthy development of urban-rural planning discipline should be based on the mutual promotion of teaching and research system.

福建农业现代化水平测度与发展对策研究

【目的】评价福建农业现代化发展水平和制约因素,提出推进农业现代化的实施路径和发展策略,为新发展阶段福建加快推进农业现代化和全面推进乡村振兴提供决策参考。【方法】运用综合指数法、层次分析法和目标值法,从产业、生产、经营三大体系和高效、绿色、支撑三大目标,构建6个一级指标和24个二级指标的农业现代化发展评价指标体系,测度“十三五”时期福建和全国农业现代化实现程度。【结果】“十三五”期间,福建农业现代化平均综合得分为66.07分,高于全国平均水平(61.21分),已迈入转型跨越中期阶段(全国平均处于转型跨越初级阶段);农业现代化水平呈现稳步上升趋势,年均增长2.18%(略低于全国2.64%的增长率)。分指标水平测度显示,产业体系和质量效益实现程度为78.38%和71.16%,分别比全国高26.07%和52.90%。生产体系、经营体系、绿色发展和支持保护实现程度分别为70.22%、 46.53%、 67.92%和41.02%,分别比全国低0.73%、 11.33%、8.77%和38.43%。福建农业现代化发展优势主要体现在农业生产效率较高、农业产业结构较合理、农产品加工业较发达、资源集约化利用程度较高等方面;而土地规模化经营水平低、农业组织经营主体弱小、农产品安全还有待提高、财政金融支持力度有限等是主要制约因素。【建议】未来推进福建农业现代化均衡发展的重点方向是:加大高标准农田改造提升力度,提高特色经济作物种植能力,加强新型经营主体和社会化服务组织培育,强化绿色防控技术推广和完善农产品质量安全体系,提高财政支农力度和优化支农资金结构,提高农业保险补贴水平和扩大补贴范围。

基于新发展理念的湖北省“十四五”期间本科层次职业学校设置策略研究

为加快完善现代职业教育体系,增强职业教育适应性,2019年,国务院出台《国家职业教育改革实施方案》,全国拉开了本科层次职业学校试点建设工作序幕。全国各地陆续申请开展本科层次职业教育试点。截至2021年12月底,教育部共批准设置30余所本科层次职业学校。然而,湖北省至今未开展一所本科层次职业学校的试点建设工作,远远滞后其他省份。我们对“十四五”期间湖北省设置本科层次职业学校的必要性、可行性及基于新发展理念的本科层次职业学校设置方案进行探讨,从而为湖北省加快完善现代职业教育体系提供参考和借鉴。

互通运营模式下轨道交通开行方案编制模型

城市轨道交通互通运营模式下行车组织呈多样化与灵活化特点,合理编制开行方案是保障运营组织效果的关键。针对互通运营模式下客流-车流耦合关系复杂化难题,建立基于开行方案的列车服务网络以刻画列车服务的差异性,构建基于乘客出行选择“策略”的客流分配模型以揭示客流-车流间复杂耦合关系;以此为基础,以运力运量匹配度最大化、运输成本最小化为目标,考虑客运服务、通过能力、运力资源及行车组织复杂性约束,将运力运量匹配关系由既有“区间”层面细化至“交路”层面,构建开行方案编制双层规划模型。最后,以北京地铁昌平线-8号线互通运营为背景开展实证分析,结果表明:所构建方法能够有效给出开行方案,满足互通行车组织需求;相比单线实际运营方案,互通方案使运输成本降低4.83%,运用车减少3组,运力运量匹配度提高27.12%。所构建方法具有良好的实用性,能够为互通运营模式下复杂开行方案编制提供方法支持。
