In addition, it is the life line of agriculture even the national economy. However, water resources face very serious situation in our country. It is shown that wafer resources are in short and the water pollution is benumbing more and more serious day by day. The reason for the problem of water resources is the management problem of water resources. Besides. the per capita water resource is low because the population is increasingly serious. The industrialization of water resources is a new conception presented due to the deepening of the social labor division and the demands of the mitigating contradiction of water resources. This paper analyzes the present situation of water resources in our country and the reasons for the problems, It expounds the important significance of the industrialization of management of water resources. Then it puts forward some saggesnons for the management of the industry of water resources, and some measure to solve those problems. 展开更多

On the basis of the analysis of the present situation of food grain and rice production in China, countering the beginning tendency to neglect rice production because of rice grain structural surplus and low market price after China’s agriculture entering the new development stage, this paper puts forward the concept of rice industrial economy, explains its attribute, connotation, key factors, etc., forms the basic idea of developing the rice industrial economy, and suggests some strategic measures such as regionalized layout of rice production,etc. to develop the rice industrial economy. 展开更多

This paper explores the improvement of the workplace environment in the context of industrialization evolution by comparing statistics from China, the U.S., Japan and other nations at various levels of economic development. The study reveals that, compared either with the U.S. and Japan at similar stages of industrialization or many developing and developed nations at different income levels, China has certain advantages when it comes to the improvement of its workplace environment. This report concludes that China is not a country with low labor standards, as is widely accepted. 展开更多

Floating production storage and offloading (FPSO) units increasingly represent a practical and economic means for deep-water oil extraction and production. Systems thinking gives a unique opporamity to seek a balance between FPSO technical performance(s), with whole-cost; stakeholder decision-making is charged to align different fit-for-use design specification options' that address technical-motion(s), with respective life-cycle cost analyses (LCCA). Soft system methodology allows situation based analyses over set periods-of-time by diagnosing the problem-at-hand; namely, assessing the antecedents of life-cycle cost relative to FPSO sub- component design alternatives. Alternative mooring- component comparisons for either new-build hulls or refurbished hulls represent an initial necessary considera- tion to facilitate extraction, production and storage of deep- water oil reserves. Coupled dynamic analysis has been performed to generate FPSO motion in six degrees of freedom using SESAM DeepC, while life-cycle cost analysis (LCAA) studies give net-present-value comparsons reflective of market conditions. A parametric study has been conducted by varying wave heights from 4 - 8 m to understand FPSO motion behavior in the presence of wind and current, as well as comparing the motions of turreted versus spread mooring design alternatives. LCCA data has been generated to compare the cost of such different mooring options/hull conditions over 10 and 25- year periods. Systems thinking has been used to explain the interaction of problem variables; resultantly this paper is able to identify explicit factors affecting the choice of FPSO configurations in terms of motion and whole-cost, toward assisting significantly with the front-end engineering design (FEED) phase of fit-for-purpose configured FPSOs, in waters off Malaysia and Australia. 展开更多
