厦门城市空间拓展的生态敏感性评价 总被引：1，自引：0，他引：1
在综合分析海湾型城市自然生态与社会生态属性的基础上,选取了高程、坡度、河流水库、植被覆盖、土地覆盖和生态保护区等6个因子,作为生态敏感性评价的指标。另外,借助GIS空间分析单因子评价与多因子加权综合评价方法,研究了生态敏感性程度及其空间分布特征,将厦门的生态敏感性划分为4级:不敏感、较敏感、中敏感和高敏感。综合评价结果表明,厦门市生态敏感性在空间分布上差异显著:高度敏感区占研究区总面积的28.1%,低敏感区和不敏感区分别占研究区总面积的27.9%和33.6%。中度敏感区占的比例较小,仅为10.4%。 相似文献

工业用地是区域土地利用的重要组成部分,也是影响区域土地集约利用的关键因素。以江苏省阜宁经济开发区为例,从系统集约度及协调度出发,研究区域各工业行业的集约度及协调度,结果显示:阜宁经济开发区工业用地整体处于低效利用水平,工业土地利用协调性处于轻度失调状态;主导行业机械机电业用地的集约性、协调性都较差;电子电工、纺织服装及食品饮料业用地规模较大且集约性、协调性超过区域平均水平,可作为阜宁开发区未来重点扶持发展的行业。 相似文献

The paper attempts to answer the following key question: how will a city′s world rank change in the face of crisis in its main economic sector? Crisis is defined here as a decline in financial performance in the given sector, which leads to the decline of its constituent firms and corporations on the world economic scene. The World Economic Center Index(WECI) has been created in order to rank cities based on the value of their resident corporations by sector and show their level of stability upon the removal of the most important sector. This provides information on the potential of each analyzed city as well as on its advanced features or area of specialization. Research has shown that nearly half the World Economic Centers are dominated by the financial and materials sectors of the economy. Different sectors dominate different regions of the world. For example, consumer staples and materials were dominant in North America, while information technology and financials were dominant in Europe. In Asia, several sectors tend to dominate the economy. Research has shown that the ability of a principal economic sector to resist economic crisis largely depends on the strength of the command and control function of a city. Finally, a high globalization level of a city is a key determinant of its susceptibility to economic crisis. 相似文献

伴随全球气候变暖导致的海平面上升及沿海地区对地下水资源的超量开采,将会诱发海咸水入侵内陆地下水,导致海陆过渡带的迁移,影响区域社会经济及水资源安全。该文以山东半岛蓝色经济区为研究背景,选取区域内龙口、招远滨海区域作为研究区,首先对研究区内的地下水流场规律进行刻画,然后以模拟因子,对目前地下水超采情景下的海陆过渡带迁移规律进行量化分析研究,研究结果表明:龙口、招远滨海区域海陆过渡带的宽度约为1.5～4.5km,且内陆地下水位越高,海陆过渡带向内陆迁移的速度越慢、范围越小。该成果对研究山东半岛蓝色经济区海陆过渡带的迁移具有重要指导意义。 相似文献

Industrial transformation of Shenyang city 总被引：2，自引：0，他引：2
ZHANGPing-yu 《中国地理科学(英文版)》2003,13(3):216-223
Industrial transformation represents a unique economic phenomenon in China‘s regional economy,and old industrial city reconstruction has long been a key problem that affects state security. As a typical old indus-trial city in China, Shenyang established its heavy industrial city position in the First Five-year Plan period (1953-1957), and this industrial structure has been consolidated for a long time. After 1978, Shenyang began its long last-ing industrial reconstruction in an all-round way by 3 main initiatives including restructuring economic system, up-grading traditional industrial technology and developing high-tech industry. In the end of the 1990s, it could be i-dentified that remarkable structural changes took place in city economy at large as well as individual industrial sec-tor. According to the GDP proportion change, Shenyang is on the way to a high level industrial structure. The sec-ondary industry also engendered significant shifting as smelting and textile industry declined sharply but IT industry increased largely. Although the ratio of the heavy industry to the light industry changed periodically, the heavy in-dustrial output value most time kept a high proportion over 60% of the gross industrial output value in the past five decades. Shenyang has favorable conditions for developing equipment manufacturing industry, but it should carry out the program by establishing its leading role in urban economy plan, building “Theme Industrial Parks“, improv-ing Tiexi Industrial Zone, removing any kind of system barrier, enlarging private and other ownerships economy and improving technology, marketing and management by IT application. In response to economy globalization,Shenyang needs to expand the cooperation worldwide and improve the cohesion with surrounding cities. 相似文献

The urban development is a decisive factor for the landuse of the territory of Hong Kong, as a realm of a world city. A speed-up
change of the landuse structure of Hong Kong and some contradictions in the landuse have been revealed after a brief mentioning
of the characteristics of the limited land resources of Hong Kong. Hong Kong consists of peninsula and islands dominated by
hilly terrain in south subtropical zone, 84% of the total area is slope, unfavorable for urban and agricultural development,
only 16% is small plains. The land is barren and water resource is very limited. Urban landuse is taken as the dominant factor.
Due to the expansion of the scale of the urban development, and the limitation of the land resource, there is a high degree
of the urban land utilization, but the proportions of commercial and industrial landuse are not high, only 1.3% of the total
developed land is used for commerce, 6.0% for manufacture industries, the road and railway lands amount to 14.6%. The great
efforts were made in reclamation and construction of reservoirs in order to add land and water resources. The arable lands
were reduced heavily and the farmlands were wasted seriously. The author proposed some view points on the present and future
landuse in Hong Kong as follows: 1) the urban landuse remains as a guiding factor in the landuse of the whole territory of
Hong Kong; 2) one of the problems is the fondness for the reconstruction of the old city, loosening up on the new town development;
3) the reclamation is not only very costly, but also causing some negative effects on the eco-environment; 4) the problem
of the protection of the farmlands against wasting should be seriously; 5) the development and the landuse for the construction
in Hong Kong should be considered with the relationship with the inland, especially Guangdong Province; 6) fully use the convenient
condition of the territorial linkage of the city with the mainland, further to bring the role of the Shenzhen Special Economic
Zone into fully play for solving the landuse problems in the development of Hong Kong.
The author is very grateful to Dr. David K. Y. Chu and Dr. Roger Chan for their comments and to Professor Gu Chaolin and Mr.
Hu Tianxin for their helps in data collection. 相似文献

夜间经济是一个城市经济发展和消费水平的重要表征。目前国内外研究者对夜间经济的研究多停留在理论层面,或基于市场调研和问卷调查的小范围精细化研究。本文融合多源数据为夜间经济提供了新的视角,相较于传统的调查数据,具有更加快速、高效、广泛的特点,适合于夜间经济大范围研究。本文基于夜间灯光、POI、OD流等多源数据,采用DBSCAN、K-Means++等空间聚类算法和研究供需关系的盈亏法,分别从消费者角度和商户角度识别厦门市夜间活动热点区域和夜间服务设施分布区域,分析厦门市夜间经济时空分布格局及相关性。研究表明:① 厦门市夜间活动在空间上呈多环状分布并向四周递减,夜间活动热点区域分布受假期的影响因地而异;② 厦门市部分区域已有服务设施未能很好地服务于夜间经济,现有的照明、夜景等夜间灯光基础设施存在供给不足之处;③ 居住人口密度与夜间活动密度呈中度正相关,研究结果具有有效性,夜间服务设施盈亏值及数量、夜间灯光与夜间活动密度呈中、弱度相关,并且餐饮设施更加依赖于夜间灯光。最后,为厦门市未来夜间经济建设提出了根据不同的消费人群和心理提供不同的夜间服务、加强夜间灯光基础设施建设以及市场扶持的举措。研究结论对促进社会就业、增强基础设施使用率有积极意义,同时也能够为城市夜间经济发展和政策制定提供参考。 相似文献
