Spatial Pattern Evolution and Industrial Characteristics of Economic and Technological Development Zones and High-tech Industrial Zones in China

Economic and technological development zone and high-tech industrial zone are important types of development zone in China,and there are differences in their connotation and goal setting.In this paper,basic data of national and provincial economic and technological development zones and high-tech industrial zones in China were collected and arranged.Kernel density analysis and other GIS spatial analysis techniques were used to analyze the evolution laws of spatial patterns of economic and technological development zones and high-tech industrial zones in cities from 2006 to 2018.First,the agglomeration intensity was compared by measuring the degree of regional agglomeration and dispersion on the two time nodes.Next,kernel density method was used to explore the evolution of the two in the spatial layout and location,and analyze development commonness and difference of economic and technological development zones and high-tech industrial zones.Finally,the trend and reason of spatial evolution of development zones with different leading industries were explored.Research results show that:①the agglomeration degree of layout of high-tech industrial zones is stronger than that of economic and technological development zones,and there are similarities and differences in distribution trend of spatial patterns of the two types of development zones;②the distribution of labor-intensive,capital-intensive and technology-intensive development zones is concentrated at smaller scales and dispersed at larger ones;③although there are differences between the economic and technological development zones and the high-tech industrial zones in the goal,support,structure and function,management system and so on,their spatial development presents a trend of convergence.In the future,when enhancing urban-rural planning and public administration,governments should combine the trend of industrial transformation and upgrading,and optimize spatial layout of development zones by adjusting industrial structure,layout,transportation and land use.

Nanjing High-tech Industrial Devel-opment Zone It is a state-level high-tech in-dustrial development zone approved by theState Council, with an area of 16.5 sq km,comprising seven sq km of industrial area,five sq km of Taiwan invested area, three sqkm of university teaching and scientificresearch area and 1.5 sq km of compositeservice area. The development zone is 13.5 kmfrom the city center, with convenient trafficconditions, three state highways and a pro-

A Study of the Industrial Development in Huazhong Agricultural High-tech Industrial Development Zone

This paper illustrates the current situation and problems concerning the industrial structure in Huazhong Agricultural High-tech Industrial Development Zone,and analyzes the internal contradictions that exist in industry: small-scale land operation has become an inherent obstacle to the industrial development in Agricultural High-tech Zone; farmers are always in a passive position in industrial restructuring optimization; government's policy failures and rent-seeking behaviors have hindered industrial development; the research,popularization and application of agricultural science and technology is not suited to industrial development requirements. Finally,this paper makes the corresponding recommendations for industrial development in Huazhong Agricultural High-tech Industrial Development Zone.

Planning mode and realization path of regional characteristic ecoindustrial park

Starting from the regional characteristic industrial park planning plan,a horizontal comparison of domestic and foreign typical urban regional industrial park planning cases is carried out,and the commonalities characteristics are analyzed to explore the regularity and universality of the Tonghua urban characteristic industrial park.Under the guiding principles for planning and development of ecological industrial parks,the city’s resource advantages,industry goals and positioning are studied and analyzed from the perspectives of the government,market,and enterprises.It is pointed out that the government should formulate policies,regulations and the construction of characteristic industrial parks in combination with new planning methods.The market should build industrial parks with the support of industrial stimulus and technological innovation.Finally,it summarizes the realization path of regional characteristic industrial parks from five aspects:positioning and goals,ways to achieve goals,profit models,customers and values,basic advantages and exclusive resources.

汽车产业园区生态化模式研究与应用——以长春市汽车产业开发区为例

汽车产业属于资源和能源消耗型产业,作为长春市支柱产业的汽车产业在推动长春市经济发展的同时也引发了相应的环境问题,长春市汽车产业开发区是具有较高产业集聚度的汽车产业共生体,可以作为生态产业园区建设的良好载体,研究其生态化改造,对长春市汽车产业的可持续发展具有重要意义。因此综合国内外生态产业园区规划的方法与手段,基于长春汽车产业开发区现有的产业发展基础及资源回收与综合利用体系,通过生态链设计和系统集成对长春市汽车产业开发区生态化改造进行了总体框架设计,并在此基础上对生态功能划分、代谢分析和物质平衡核算以及空间布局进行了研究,最后在对园区建设的效益予以估算及评价的基础上提出生态产业园区未来发展可能存在的问题及初步的对策建议。

吉林省设立综合配套改革试验区刍议

从特区到开发新区再到综合配套改革试验区的发展过程是从争取国家给予政策支持到争取国家给予发展自由度的过程。吉林省资源丰富,但经济社会发展中却没有亮点,缺乏超常规发展的契机。因此,在国家将实行更加宽松的政策和更大的自由度来发展试验区的形势下,吉林省要紧紧抓住这一有利时机,积极争取综合配套改革试点,以此作为区域发展的新契机。

长春高新技术产业开发区道路绿地园林植物多样性研究

以长春高新技术产业开发区道路绿地为调查对象,研究园林植物多样性,结果表明:该区道路绿地共栽植园林植物30科52属86种,一级、二级和三级道路绿地园林植物多样性Shannon-Wiener指数平均值分别为1.6、1.1、0.7,二级和三级道路绿地的植物多样性指数有待提高。外来物种或品种使用较多,乔木有13种,占道路绿地乔木种类的26.6%;花灌木5种,占花灌木种类的12.5%;宿根花卉3种,占50.0%;冷季型草坪全部为外来种,乡土物种的使用比例有待提高。
