An Interval Fuzzy Multiobjective Watershed Management Model for the Lake Qionghai Watershed, China

Integrated watershed management is required to ensure the reasonable use of resources and reconcile interactions among natural and human systems. In the present study, an interval fuzzy multiobjective programming (IFMOP) method was used to solve an integrated watershed management problem. Based on system analysis, an IFMOP model suitable for a lake watershed system {IFMOPLWS} was developed and applied to the Lake Qionghai watershed in China. Scenario analysis and an interactive approach were used in the solution process. In this manner, various system components were incorporated into one framework for holistic consideration and optimization. Integrality and uncertainty, as well as the multiobjective and dynamic characteristics of the watershed system, were well addressed. Using two scenarios, two planning schemes were generated. Agriculture, tourism, macroeconomics, cropland use, water supply, forest coverage, soil erosion, and water pollution were fully interpreted and compared to identify a preferable planning alternative for local agencies. This study showed that the IFMOPLWS is a powerful tool for integrated watershed management planning and can provide a solid base for sustainable watershed management.

区港合一与厦门港城经济发展

区港合一指的是保税区、港口码头作业区实行一体化运作,在货物监管上采取一线放开、二线管住、区内宽松的自由贸易模式。按照构想,在厦门实行区、港合一,主要是充分利用象屿保税区坐落在东渡港区、区内无居民而便于实行隔离监管的优势,将象屿保税区与东渡港区进行组合,形成一体     

诚信从这里走来

众所周知,注册会计师是市场经济秩序的重要维护者.独立、客观、公正地出具审计报告是其基本职责,也是注册会计师职业道德规范的基本要求.离开公正、诚信,会计信息就失去价值且危害社会.     

新时期广东省山区人口控制探析

20世纪90年代以来，广东省的山区人口增长速度虽然得到了控制，但与珠江三角洲相比还存在一定差距，地区之间发展也不平衡，生育水平仍不稳定，有效的人口控制机制尚末真正形成。因此，必须建立保障体系 和切合实际人口控制工作新机制，把人口控制工作寓于服务之中；加强计划生育队伍建设，提高队伍整体素质和工作效率。     

SIMILARITY LAW OF FLUCTUATING PRESSURE WITHIN HYDRAULIC JUMP AREA

Through a series of model tests of five scales for 2-D free hydraulic jump, the da-ta of fluctuating pressure acting on the floor level within the hydraulic jump were obtained. Dur-ing the experiments, Froude number varied from 2.94 to 8.61, and Reynolds number rangedfrom 2×10~4 to 6×10~5. Experiment results indicate that the amplitude scale of fluctuating pres-sure is the length scale of model, i. e. P'=L, which agrees with gravity similarity law: Thefrequency scale of the fluctuating pressure is a unity i. e., f=1, which does not satisfy thegravity similarity law.     

关于供排水管网的水力计算和校核

以往对电站技术供排水系统大都未进行水力平差计算，致使一些实际电站的供排水系统达不到预期的效果，甚至影响机组的正常运行。据此，给出了供排水管网的平差计算方法，有利于正确评估电站管网，另外，提出了管网校核应注意的问题。
