Sustainable management of a coastal lagoonal system (Ria Formosa, Portugal): An ecological model for extensive aquaculture

The Ria Formosa lies in southern Portugal, extending for about 55 km. It is a true barrier island system, comprising mainland, backbarrier lagoons, inlet deltas, barrier islands, barrier platforms and shoreface. Of the Ria Formosa system, which covers a total area of 163 km², 20 km² are occupied by salinas and aquaculture ponds. The main water reservoir of thesalinas and the extensive aquaculture ponds behave like small lagoons where there are one or more openings to a tidal channel. These small lagoons have the advantage of being easy to study and to model. An ecological model was developed to estimate the potential production of the gilthead seabream in the Ria Formosa, in an extensive aquaculture regime. This model was based on information concerning chemical and physical factors (forcing functions) and secondary production estimates from four sites in the Ria Formosa with different environmental conditions, where extensive aquaculture is practised. Published information on optimal growth parameters of the gilthead was used to build the model, which was based on some assumptions concerning the detrimental effect of an excessive increase of salinity and other environmental factors both on gilthead growth (one state variable) and on prey production (divided into two state variables), which is essentially benthic macrofauna. Reservoirs with low water renewal undergo large environmental fluctuations. The growth of gilthead or other fish can be difficult, not only because of the adverse environmental conditions but also because of the low secondary production. The maximum yield of fish is predicted to be less than 6 g m⁻². In reservoirs where the water exchanges on almost every tide, the maximum yield of gilthead can be in excess of 22–25 g m⁻². Nevertheless, the high productivity of these sites in terms of secondary production of benthos and fish, as well as primary production, can lead to oxygen depletion during the night or at day-break. An attempt to further improve fish production by fertilisation or by adding food could provoke a rapid deterioration of the water quality and endanger all production.

内陆待开发地区产业发展模式探讨——以内蒙古为例

以内蒙古为例，探讨了内陆待开发地区的产业发展模式，内陆待开发地区经济发展的主要制约因素是缺乏资金，缺乏技术，缺乏人才，因此，其经济发展必须有选择，有重点地优先发展部分行业。一般说来，待开发的内陆地区其经济发展必须以资源优势为依托，以市场为导向，开发优质名牌产品，发展优势产业，建设主导产业，带动地区经济的起飞。     

The Organization of Production in High Technology Industries: An Empirical Assessment*

Recent attention given to the concept of vertical integration and disintegration of production processes has identified the existence of a continuum, with small, flexibly specialized producers at one end and large, mass production units at the other end. Firms along the continuum constantly strive for the optimum combination of economies of scale and scope. This paper attempts to identify the organizational characteristics of high technology firms in one industrial complex of the U.S. Manufacturing Belt. A principal components analysis is performed on a number of theoretically relevant variables for a sample of high technology establishments in Northeast Ohio. The results indicate that the region contains a variety of organizational forms ranging from isolated workshops to large, vertically integrated assembly plants. These findings conform to expectations derived from recent conceptualizations in the literature. Additional empirical research will further enhance understanding of the processes that shape the organization of production in territorial complexes.

简评关于新产业区的国际学术讨论

２０世纪７０年代末和８０年代初，当发达国家的绝大部分地区陷入衰退与停滞时，少数几个地区的经济却呈复苏甚至增长的势头，这些地区在经济运作模式上的相似性，引起了研究者的兴趣。由于它们和历史上马歇尔所描述过的产业区有惊人的相似之处，学者们将他们归为一类，称之为新产业区。本文对正在向纵深发展的关于新产业区的国际学术讨论作了简要的评述，并探讨了新产业区理论在我国的研究背景与进展。     

南泥湾油田工业油流标准参数确定及算法

针对南泥湾油田特点。确定适合本区地质及油藏工程特点的工业油流标准，提高该类油田储量的计算精度。应用数值模拟、类比等方法。结果显示．南泥湾这类必须经过压裂改造的特低渗油藏．单井产量仍然按照双曲线递减规律；工业油流标准的确定，需要准确把握单井平均总投资、原油利润、收回单井总投资的单井产量等参数，在此基础上确定的工业油流标准更能满足生产需要，对储量计算、滚动开发建产、管理者决策具有十分重要的意义。     

美国"阳光带"的崛起对中国西部城市化战略的启示

美国西部开发以城市化为先导，中国西部大开发本质上也是西部城市化。西部大开发战略应以城市为中心组织与落实。本文通过透视美国“阳光带”城市崛起的历史，尤其是产业集群的成功经验，提出中国西部城市化战略实施中应将培育地方产业集群作为推动城市化的重要战略方式和地方重要的公共政策工具。
