| In the vast history of China, Ningxia Plain is one of the earlier agricultural development, the birthplace of Chinese civilization is one of our. Yellow River runs through the Ningxia Plain, where it winds through the area, the river is slightly lower than the ground, it is irrigation interests, no breaches of the risk of flooding, so the "rich world of the Yellow River in Ningxia, "said the Yellow River Created Ningxia Plain.Ningxia in northwest China secluded inland, drought, most of the people living and production facilities rely on the Yellow River irrigation water. Since the Qin Dynasty immigrants frontiers, cutting canal water, since irrigated agriculture development, the next dynasty in varying degrees, to expand the area of agricultural development, an increase of the Yellow River irrigation area, so this "Pearl of the Frontier"more Brilliant, more brilliant. In contrast to the Qing Dynasty government attaches great importance to the Government and the people for their co-Yellow River irrigation project in Ningxia Plain in even greater success, which is reflected in the new cut of the three Yellow River main channel, some water technology innovation Emergence of a group capable of Yellow River irrigation officials, a number of innovative water management system. For a time, so that the cause of the Yellow River in Ningxia boarded the historical peak.We investigate the cause of the Qing Dynasty Ningxia Irrigation made impressive achievements, but also analyzes the irrigated areas of Ningxia Qing geographical environment and farmland, some relations between water development. On the one hand, we have a bit more than on the environmental conditions and the relationship between irrigation development; Highlights a number of natural disasters on the impact of water development, such as drought, waterlogging, earthquakes and so on. Also analyzed the impact of irrigation development of some of a number of factors, such as household labor reform, reclamation policy changes and government attention and to Fangguan Min participation, which gave the cause of the Yellow River has had a positive influence. On the other hand, we note that the Ningxia Plain sustainable agricultural development through after some of the environmental changes that occur the problem; I analyzed from two aspects:The first is the development of irrigation and water conservancy from the social environment described this level, As a long-term development of the Ningxia Plain water channel intensive, irrigation network developed, a variety of property showing enriched state. Water utilities also open up, attracting a large number of immigrants settle in for a great fusion of all ethnic groups, thereby promoting the Ningxia Plain in the Qing Dynasty the great development of the agricultural economy, there are many new daily trading market to facilitate the people's lives, strengthen Ningxia border region's stability. The second point is the development from the water impact on the natural geographical environment to start, there are five aspects of contents:Cultivated type of change; the characteristics of the population distribution pattern; on some of the effects of natural ecosystems; acceleration of desertification and soil salinization increased. Analysis of these issues and put forward some ideas oThrough the above analysis and description, combined with the historical experience of mankind, we can easily conclude:Only through rational human agricultural development, water conservancy construction in order to protect will help us continue to develop and survive the human environment. Specifically, in the Ningxia Plain in the future development of irrigation and water conservancy, ecological benefits and social benefits must pay attention to the combination of water development and the environment to coordinate the sound development of harmonious relations and realize the sustainable use of Yellow River water resources, this is our the requirements of future generations. |
