Character and Causes of Population Distribution in Shenyang City, China

1 Introduction Research on the character of urban population distribu- tion is one of the focuses of western urban geography. From the 1950s, the research has attracted the attention of many western researchers, and a series of classical theoretical models were put forward. For example, Clark (1951) found that with the increase of distance from the city center, the urban population density tends to de- crease in exponential. Through the statistical analysis of more than 20 cities, he put forw…

Study of Ecological Water Demand of Rivers in Shenyang City,Northeastern China

The ultimate goal of the protection and restoration of water ecosystem is intended to facilitate the healthiness of ecosystems in rivers and lakes, and the basic premise of river healthiness is to ensure the ecological water demand of rivers. Shenyang City is the economic and cultural center of Northeastern China, and most rivers in the territory of Shenyang City are plagued with the ecology and environment problems such as dry-up of river way, wetland shrinkage and groundwater overdraft. In protection and restoration of water ecosystem, Shenyang City should first study the ecological water demand of rivers. In this paper, we first defined the connotation, composition and calculation method of ecological water demand of rivers and selected eight major rivers in Shenyang City for ecological water demand study and calculation according to the characteristics of the rivers and water resources conditions in Shenyang City. We calculated the basic eco-environmental water demand and consumptive water demand for evaporation and seepage of river ways respectively and thus obtained the total eco-environmental water demand for eight rivers. In total eco-environmental water demand of rivers, consumptive water demand for evaporation and seepage of river ways accounts for 51% and the eco-environmental water demand of rivers accounts for 49%     

沈阳地区河水及沿岸地下水中卤代烃的污染特征

选择沈阳地区主要河流(浑河、蒲河、细河、沈抚灌渠)地表水及其沿岸地下水进行卤代烃的定量分析,研究并探讨了卤代脂肪烃和卤代单环芳烃的污染分布特征。浑河和蒲河河水中卤代烃检出率较低,以二氯甲烷为主,检出率为33.3%。检出率高值区主要在细河和沈抚灌渠,13种卤代烃被检出。在30个站点地表水样品中有6个站点卤代烃个别化合物浓度超过我国生活饮用水卫生标准。在13个监测井中,有1个井水的1,2-二氯乙烷浓度(101.1μg/L)超标。卤代烃污染以细河上游和中游以及沈抚灌渠上游最为突出。在细河上游大于镇和中游彰驿镇河水中卤代烃的含量较高,可能与沿岸化工企业有关。沿岸土壤层中砂层为受污染的河水对浅层地下水的补给提供了条件,造成浅层地下水污染,对当地生态系统和人类健康构成潜在的威胁。     

沈阳-大连区域旅游"双核"结构模式探讨

区域旅游是旅游发展的必然趋势,空间结构是区域旅游研究的重要内容。"双核"结构是一种比较高效的区域空间结构形态,由某一区域内的中心城市和港口城市及其连线所组成。这一理论提供了一种区域旅游发展空间结构及旅游城市间相互作用机理的解释模型。沈阳和大连在区域旅游发展过程中形成了典型的"双核"结构。文章着重分析了两市形成旅游"双核"结构的基础及耦合机理,以期使"双核"理论在旅游发展中起到抛砖引玉的指导作用。     

老工业城市产业转型及其就业变化研究——以沈阳市为例

老工业城市产业转型是区域经济中的一个独特现象,其成功与否将直接影响区域经济的发展。文章在深入分析老工业城市产业转型与就业变化两者互动关系的基础上,以典型的老工业城市沈阳市为例,探讨了沈阳市产业转型过程中的产业升级、产业替代和产业融合,对城市就业结构、就业制度以及就业文化方面的影响。最后总结了老工业城市产业转型与就业变化的特征,讨论了沈阳市在产业转型过程中促进就业的对策措施,以此为东北地区老工业城市产业结构的调整和就业政策的制定提供科学依据。     

Study on forecast scenarios for simulation of future urban growth in Shenyang City based on SLEUTH model

The SLEUTH urban growth model was used to simulate future urban growth patterns and to explore potential environ-mental impacts of urban development under different conditions of development in Shenyang City, China. The SLEUTH model was calibrated with historical data (1988-2004) extracted from a time series of TM satellite images, and the future growth was pro-jected out to 2030 assuming three different policy scenarios: (1) current trends scenario (Scenario CT), (2) regional policy and ur-ban planning sce...     

基于Landsat卫星的沈阳市土地覆盖变化研究

土地利用、土地覆盖变化(LUCC)是当今遥感领域的重要研究课题,也是地学界、生物学界、环境学界等关注的热点问题之一^[1]。特别是对大城市的土地类型变化研究,有利于揭示城市化进程中的空间变化规律。本文利用沈阳市1990、2000、2010年3期Landsat系列卫星数据,经过空间配准、相对辐射校正、图像增强等预处理,分别对3期遥感图像进行监督分类,提取土地类型转换信息并进行景观格局分析^[2]。结果表明,20年间沈阳市土地覆盖变化主要表现为耕地和建筑用地的转变,其中1990—2000年,耕地和建筑用地均有缓慢增加;而2000—2010年耕地面积明显减少,建筑用地显著增加,城市化进程大大加快。本文成果对沈阳市未来城市规划和可持续发展相关政策的制定有一定的参考价值。
