known as “kidney of the Yangtze River”, China’s largest freshwater lake, Poyang Lake, the current difficulties facing the water, full of an unprecedented water crisis and drought, the lowest water level has fallen below 8 m, the highest 60-year low water, lake basin area wet period only 1 / 20, local officials said, to build locks to solve the Poyang Lake water crisis a priority. (January 31, the Guangzhou Daily)
Yangtze water quality and watershed in recent years with the deterioration of ecological environment, water shortage in the dry Lake normalization problems frequently occur. Effectively resolve the Yangtze River basin of the Great Lakes ‘water crisis’, by the construction of the dam gates “Curb” is indeed an unwise move, the normalization of the dry Lake resolve the problem can not rely on human nature, subjective, “Curb, water” and other short-term effect of strategy, a fundamental long-term perspective of the Yangtze River Basin from the Great Lakes to promote the ecological environment and the natural cycle of water is the best policy.
undeniable, behind the lake is extremely dry, under a variety of factors, normalization of ecological water shortage, and the destruction of the Great Lakes waters are quite common in 2008, there have been dry four times a year seasonal phenomenon rarely seen in history. Objectively speaking, the Poyang Lake in recent years, although there are frequent low water less than normal rainfall and other natural factors, the whole reason, but human, subjective factors are leading to environmental damage a large area of Poyang Lake water source dry normalization, in which Lake waters of large-scale sand mining operations and a large dam on the Yangtze River Lake “pull air” effect, is caused by longer dry season, dry area to expand the main reason.
as the breadbasket of the Poyang Lake water, the norm of the low water has been pressing for China’s water conservation sounded the alarm, if you do not take early and effective ecological management and environmental protection measures, China is facing more serious water crisis. According to statistics predict that by 2030 China’s total water consumption will reach 700 billion -8 000 billion cubic meters, while the national arena when the actual availability of water resources is only about 800 billion cubic meters, which is close to water resources development and utilization of nature the limit.
of “Curb” way to resolve the biggest drawbacks is the low water: first, to cut off the subjective nature of human natural circulation system of rivers and lakes, likely to cause “dead lake”, lead to even more serious ecological damage to the environment, causing nature of the food chain breaks; second, the dam, “Curb,” the fundamental purpose is “water”, while the norm of the Yangtze River water rivers and lakes, the key is to maintain natural water balance and auto-loop upstream of the natural river water discharged ; Third, the construction of sluices, “Curb” will inevitably lead to the Yangtze River below Lake artificial river water, which is a “shattering” of the dry style of governance, is typical of local protectionism worst strategy.
the relationship between man and nature, should be harmonious and adapt, rather than confrontation transformation. We are able to transform nature’s natural eco-cycle system, to transform all subjective, harm the environment by the nature of economic activities will be punished. From the perspective of long-term interests of future generations, to resolve the normalization of Poyang Lake waters the best way to dry or should increase its natural flood storage capacity of water resources and ecological services functions, to as industrialization, urbanization and deteriorating fast forward the original environment to minimize the negative impact.
