. Less water valley, dam variation coefficient, generally above 0.4, while the more mountainous areas of water less coefficient of variation in 0_23. Changes in the Yangtze River coefficient of variation of 0 ~ 8 - 0.48 of the question, the Pearl River between 0.23 and 0.4. There is still a continuous water or less water and more water changes. More water and less water, usually a long cycle for 3 consecutive years. Seven of the Yangtze River Bridge Station, 37-year runoff, there have been for 4 years (1954 - 57 years) and for 3 consecutive years (1964 - 66 years) multi-water period. During these two years the average annual flow of more than 25.1% and 42.1%; also appeared in 6 consecutive years (1980 ~ 85 years) and for 3 consecutive years (1987 - 89 years) of less water , these two periods, the average annual flow of 22.4% less than the average for many years and 444%. Pearl River West Bridge station, 38-year runoff, there have been 4 years of a relentless give an example of a 36 h ● ● (1954 ~ 57 years) and for 3 consecutive years (1964 ~ 66 years) and more water period, these two period of years the average annual flow of more than l6% and 42.5%; also appeared in 5 consecutive years (1980 ~ 84 years) and for 3 consecutive years (1987 ~ 89 years) low water period, the two periods Ping Mu years of average flow of less than 17.1% and 52.6%. 89 years from 1987 to the low water period, the whole region in general drought, severe water shortages, industrial and agricultural production and have significant impact on people's lives. 4, natural water quality and water pollution in the industrial and agricultural production developed rapidly, as people have ignored the problem of pollution, pollution of major rivers Qujing increasingly prominent,dfgdfdsfs, water quality becomes worse, especially in industrial concentration,ugg boots, population density, the larger South Jiangbei Panjiang plate. Kraal River region at a serious Nanpanjiang light surface water pH values range from 7.5 ~ 1l9, total hardness 8.4 ~ l23, 584 to 909 degree of mineralization in the South for the disk monitoring sections of the river , Zhanyi prescription Bridge, Victoria Bridge, the two monitoring sections, pollution index was 33.93 and 7.24, respectively, stained mattress grade V destroyed. Is a serious pollution, is the territory of the most polluted section of the river along the side of Qujing bridge, Luliang ring dams, pollution levels are very v, which is heavily polluted; Luliang West Bridge pollution level is Ⅵ level. Moderate pollution; Huashan reservoir outlet section, contamination levels for the I level, is clean water. Beipanjiang PH value of the surface water ranges from 8.5 to 10.2, with a total hardness of 84 to 9.5, salinity 3.30 ~ 8.15. Monitoring sections of the bridge from the Sherwin Datun of view, pollution index is 1.91, pollution grade Ⅲ, light pollution and other pollution monitoring section for the I-level class, is clean water. Kraal River PH value of the surface water ranges from 8.3 to 9.2, total hardness 10.2 ~ l3.6,. Salinity of 3.12 ~ 8.78 from the Great River Bridge monitoring sections to find mid-term, 'pollution index was 056, pollution grade Ⅱ, is a relatively clean water. 37 - Second, groundwater resources, the total amount of groundwater resources in Qujing 382l billion cubic meters, accounting for 239% of total water resources; the amount of groundwater resources in the province accounted for 5.2%, higher than that of Lijiang, Dali, Chuxiong, Yuxi, Kunming, Dongchuan, ranking eleventh province runoff modulus G 3.72 L / s - kilometers, less than the provincial average, higher than the Dali: Yuxi,uggs, Kunming, Chuxiong, ranking thirteenth province bit. Total amount of groundwater resources in Qujing not rich, but more uniform regional distribution, a more stable inter-annual changes in the characteristics of the year. Eight counties and one city in the region, the groundwater water yield per unit area is the most Luo County,ugg boots, 18.21 million cubic meters per square kilometer, the amount of groundwater resources 221% of total resources; ground water yield per unit area for at least the Mayo County , 5.52 million cubic meters per square kilometer, the amount of groundwater resources l5.6% of total resources per unit area of groundwater district average water production l1 million cubic meters per square kilometer. In addition to Malone, the carbonate rocks distribution Luliang area is less water outside, and the remaining counties are in the water area. With the rapid economic and social development and progress of industrial and agricultural water demand will Qujing a substantial increase in industrial and agricultural water use conflicts will be more prominent, while the further development of industrial and agricultural water pollution may also extend the a deeper level, conflict is exacerbated by the development of the new situation and requirements, we must follow the characteristics and laws of the situation of water resources, development of water resources development and utilization of care management planning, so that a reasonable development, make full use of water resources, enhance water resource conservation and integrated management, protection and management of water resources incorporated the legal system, so the limited water resources to maximize service to the people to adapt and promote national economic development. 相关的主题文章： moncler online Control of power load management sy ugg Günstig Urgent need for the media industry, r moncler online shop Water Resources Development an |
