东营市南展区砂岩热储地热回灌量与温度的关系探讨

东营地区地热资源丰富,主要开采层位为新近纪馆陶组、古近纪东营组,热储类型为低温温热水、热水型层状孔隙-裂隙型砂岩热储,地下热水补给条件较差。近年来,随着地热资源的开发利用规模的加大,开采密集地带的热水头明显下降,存在资源枯竭,引发地质环境问题的威胁。采用回灌方式补充地下水源,是实现地热资源可持续利用和地质环境保护的有效措施。为研究该区地热回灌可行性与回灌制约因素,在南展区开展了多次回灌试验,试验表明,该层热储回灌空间大,回灌条件较好,压力对回灌效果影响明显,回灌水体温度对回灌效果影响较大。利用回灌量与回灌水头之间的影响关系,模拟计算不同温度下回灌水头的变化情况,探讨了回灌量与回灌水体温度的影响关系,对回灌研究具有一定的指导意义。

黄河南展区工程管理存在的主要问题及对策

“十二五”期间，随着黄河标准化堤防建设力度的加大，各项防洪工程标准的提高，各级领导对工程管工作越来越重视。由于历史的原因，南展区内的诸多遗留问题尚未得到解决，造成展区工程面貌依然如故，从而影响了堤防工程整体水平的提升。本文指出了南展区工程管理工作存在的主要问题，提出了解决的对策与建议。

Resource and Environmental Quality Changes and Adjustment Principles for Sustainable Development in Rapidly Developing Coastal Region of Southeastern China

Problems in water-land resources and environmental quality increase with the fast economic development in the coastal region of southeastern China. This region has the highest density in population, industry and towns in China, and the large export-oriented economy makes itself a strategic importance while China enters into international markets. The problems facing to this region include arable land reduction, land degradation aggravation, high percentage of built-up land with high rate of expansion, expanded non-point pollution, deteriorated water quality, decreasing biodiversity, destroyed ecosystems, severe air pollution, frequently occurred acid rain, and multi-pollutants. The important research fields in the near future should include a) influence of high-intensity exploitation of resources on changes of environment quality and its feedback; b) interface processes, key mechanisms and adjustment principles for degradation of water-, land-, and air-resources and environmental quality; c) evolvement processes and nurturing theory of biodiversity and ecological resources; and d) spatio-temporal variation and human-induced effects on regional resources and environment quality. Strategies for sustainable development in the region are as follows: a) controlling to ensure basic cultivated land area; b) enforcing remediation of polluted water environment, and controlling non-point pollution; c) strengthening ecological construction and ecological security; and d) controlling multi-pollution and preventing trace toxic pollutants.

Economic analysis of freeway town of Yunnan

Freeway town in Yunnan is driving to promote the economic development ties.The development along the highway in the town will become the central point of the vertical and horizontal development of the area around the gradient the proliferation Point and Area.The highway town will develop to speed up the urbanization process and China should accelerate the development of the freeway town .Encouraging farmers will shift the highway town where some good conditions will build to form a regional economic development and growth .This will be the promotion and inevitable choice of progress and rational way of China＇s rural economic and social prosperity.In particular,freeway town will bring more added value of other social services of accommodation and catering industry of wholesale and retail of transportation and warehousing.Highway town and agriculture industrialization development will increase agriculture industry chain to improve agricultureal products value and will enhance agricultural efficiency in Yunnan.The concentration of the non-agricultural industries of the specdway town will form pillar industries of highway town and will promote of tertiary industry development of hotels of insurance of finance of business of sports of culture of education of communications of transportation.Rural areas of Yunnan will adjust to optimize the industrial structure.It is estimated that a total 10 construction of the highway town of Yunnan will increase 08-1 billion yuan revenue each year.

Study the interaction between the development of specialized Southwest National Area Rural Tourism and New Countryside Construction

Southwest minority areas has its unique culture, natural landscape resources and post-development advantages, in recent years, the local government is developing rural tourism in order to promote local new rural construction. In practice, however, the lack of coordination measures necessary between rural tourism and new rural, leading to interoperability between the two thrust did not really been achieved. On the basis of analyzing current interaction of Liangshan rural tourism development and new rural construction, it focus more on discussing the strategy of developing rural tourism in Southwest National Area and the construction of new socialist countryside.

Strategies to Promote Sustainable Development of Industrial Parks in Vietnam＇s Northern Key Economic Zone

Industrial Parks （IPs） in the Northern Key Economic Zone of Vietnam （NKEZ） have been making significant contributions to the development of the zone since the first two industrial parks--Noi Bai in Hanoi and Nomura in Hal Phong--were established 15 years ago. So far, there have been 51 IPs in the zone, covering a total area of 13,000 ha. Such IPs play a crucial role in mobilizing capital from domestic and international investors for investments in infrastructure enhancement, trade and production aimed at promoting the economic structure transition. However, besides the above benefits, there are a number of unstable factors preventing further development of the IPs. Thus, the objectives of this study are two-fold. The first is to analyze the unstable factors, and the second is to map out strategies to enhance sustainable development of industrial parks in Vietnam＇s northern key economic zone.

Climate change regionalization in China(1961–2010)

Since climatic condition is the important foundation for human subsistence and development and the key factor in sustainable development of economy and society, climate change has been a global issue attracting great attentions of politicians, scientists, governments, and the public alike throughout the world. Existing climate regionalization in China aims to characterize the re gional differences in climate based on years of the mean value of different climate indexes. However, with the accelerating climate change nowadays, existing climate regionalization cannot represent the regional difference of climate change, nor can it reflect the disasters and environmental risks incurred from climate changes. This paper utilizes the tendency value and fluc tuation value of temperature and precipitation from 1961 to 2010 to identify the climate change quantitatively, and completes the climate change regionalization in China （1961-2010） with county administrative regionalization as the unit in combination with China＇s terrain feature. Level-I regionalization divides China＇s climate change （1961-2010） into five tendency zones based on the tendency of temperature and precipitation, which are respectively Northeast China-North China warm-dry trend zone, East China-Central China wet-warm trend zone, Southwest China-South China dry-warm trend zone, Southeast Ti- bet-Southwest China wet-warm trend zone, and Northwest China-Qinghai-Tibet Plateau warm-wet trend zone; level-lI region- alization refers to fourteen fluctuation regions based on level-I regionalization according to the fluctuation of temperature and precipitation.
