The middle reaches of Yangtze River;human-water relationship;evolution;humans activities;water environment
摘要：
This article first elaborates the evolution of human-water relationship in the middle reaches of Yangtze River. In the ancient times, natural habitats of the human species were centered around large water and grass rich areas. People maintained an orderly and complete relationship with the water-environment, with the progression of time agricultural societies, begun to exploit the Two-Lake Plains (Hunan and Hubei plains), they constructed irrigation projects and re-constructed the water environment. In Ming and Qing Dynasties, reclamation from lakes caused deterioration of human-water relationship, by the time china was declared a sovereign government, Chinapsilas human-water relationship had became comprehensively deteriorated. further more, this paper also analyzes the influence of human activities on the water environment focusing on aspects of the changes within the lakes system, the evolution of hydrological characteristics, the variation of the frequency of flood disaster and the deterioration of water quality in the middle reach of Yangtze River. The result showed that river systems of Yunmeng marsh, Dongting Lake, Poyang Lake, Jingjiang river have undergone profound changes; the runoff and the sediment content exhibited a decreasing trend in recent years. The frequency of flood disaster has also been on the increase in recent decades. The rapid development of agriculture and other industries accelerated the ecological environmental destruction and the water quality. Finally, the paper discusses the water environmental variation and its effects on human social culture, custom, architecture, settlement vicissitude as well as the agriculture and the influence of flood disaster intensification. The paper demonstrates that water is one of the necessary driving forces for social development.

摘要：
This paper studies the present state of water and soil loss in the Hubei province. Chinese scholars have analyzed the causes of water and soil loss, and pointed out that both natural factors and human activities are the root causes for these losses. The associated natural factors include the landscape, soil, groundwater and precipitation. Since the climate in this area is subtropical monsoon, heavy rainfall occurs during summer and as a result, the greatest water and soil loss mainly takes place in this season. Hubei province is divided into three regions according to the degree of water and soil loss. The first region is that of mountainous areas given its landscape, this area is characterized with serious water and soil loss. The second region features agriculture and industrial activities, the original land surface area in this region is greatly disturbed by the human activities that it is subjected to. The third division is that of the land around lakes, this division is based on the unique type of soil found in such areas. Human activities including the land use in the agriculture and urban expansion, is found especially in mountainous areas. Research has established that water and soil loss has since 1980, increased more and more with the passing of time. It can be concluded that this trend will continue if the human activities do not support the soil and water systems. Finally, the results from the prevention and treatment discussed showed that the control measures for the prevention of water and soil loss must be definitively enforced at the earliest convenience.

The Construction for Guarantee;Early Warning;Water Pollution Emergencies
摘要：
Water pollution incidents have taken place in China frequently resulting in an enormous economic loss. How to solve the problem timely, effectively and efficiently becomes a significant issue to scrub the deleterious effects of sudden pollution accidents. Emergency pollution incident management system is a complete system composed of data layer, model layer and the system interface layer. It has early warning functions such as the real-time monitoring of water quality and prediction of pollution emergencies. To take Wuhan city for example, this system realize the function of attribute query, mouse fixed-point tracking, input of incidents site and output of transportation process as well as extension of pollutants cluster from time to time. It can also query the water quality in different time. The system can be enhanced profoundly and will shorten the response time in a large scale. The successful control methods provide references and technical support for watershed management of pollution accidents in other area.

摘要：
Safe and reliable drinking water is vital to every community. But water pollution incidents have taken place in China frequently resulting in an enormous economic loss. How to solve the problem becomes a significant issue to scrub the deleterious effects of pollution accidents. So the establishment of response models of water pollution accidents in Wuhan city is necessary in order to enhance rapidity, effectiveness and accuracy of emergency commanding, and to improve the level of scientific decision-making. As emergency pollution management system is a complete system composed of data layer, model layer, the system interface layer and network layer. It also has early warning functions such as the real-time monitoring of water quality and water quality prediction of water pollution accidents. Early warning and emergency response system for water pollution accidents in Wuhan City, China shows a quick-acting and accurate numerical method to calculate the value of pollutant concentration in a short time.

Frequency;Precipitation days;Trends;Yangtze river basin.
摘要：
This paper explores the frequency of precipitation days to better understand flood potential by using different percentiles in the Yangtze River basins from 1950 to 2000. The positive (increasing) trends of the precipitation days at the 75th and the 95th percentile are analysed on both yearly and decadal scales. Some interesting facts have been revealed through this study. It is observed that the precipitation days at the 75th percentile increase more than that of the 95th percentile in the basin. This explains that the yearly increasing precipitation is due to excessive rains and not heavy rains. Also, through the trends (positive and negative), the variation of yearly precipitation days can be classified.

摘要：
Watershed, as it comprehensively represents any part of water resource on our land, is considered the most appropriate units not only for the assessment of water environment, analysis and usage of water resources, but also for the management of water quality. Therefore, many scholars use watershed management to deal with the arising water problems and maintain sustainable development at watershed scale. Considering the complication and uncertainty of watershed system, previous scholars began to use various newly-built models to fulfill the task of watershed management, that is, the multi-objective optimization watershed management models. These models enable us to view watershed management from environmental, economical and social aspects. Base on the study of these models, this paper comprehensively concludes the mechanics, feature and methods of the models. Especially, we analysis four applications of multi-objective optimization models in watershed management. Finally, we analysis the problems of the existing models and express our expectation of the development of multi-objective optimization watershed management models in the future.

Annual maximum streamflow;El Niño/Southern Oscillation (ENSO);Wavelet approach;Yangtze River basin
摘要：
Variability and possible teleconnections between annual maximum streamflow from the lower, the middle and the upper Yangtze River basin and El Niño/Southern Oscillation (ENSO) are detected by continuous wavelet transform (CWT), cross-wavelet and wavelet coherence methods. The results show that: (1) different phase relations are found between annual maximum streamflow of the Yangtze River and El Niño/Southern Oscillation (ENSO) in the lower, the middle and the upper Yangtze River basin. In-phase relations are detected between annual maximum streamflow of the lower Yangtze River and anti-phase relations are found in the upper Yangtze River. But ambiguous phase relations occur in the middle Yangtze River, showing that the middle Yangtze River basin is a transition zone. Different climatic systems control the upper and the lower Yangtze River. The upper Yangtze River is mainly influenced by the Indian summer monsoon and the lower Yangtze is mainly influenced by the East Asian summer monsoon; (2) as for the individual stations, different phase relations are found in the longer and the shorter periods, respectively. In the longer periods, the annual maximum streamflow is more influenced by climatic variabilities, while in the shorter periods, it is influenced by other factors, e.g. human activities. The results of the study provide valuable information for improving the long-term forecasting of the streamflow using its relationship with ENSO and the Indian Monsoon.
