Effect of Water Allocation of the Heihe River on Plan Structure and Stable Development of the Ecosystem in the Linze Oasis, Gansu ——A Case Study in the Pingchuan Irrigation District in Linze County at the middle reaches of the Heihe River

Water allocation of the Heihe River and commercial utilization of water will exert a profound influence on adjustment of plant structure, water save and conceding the land in the Linze oasis. However, there are some problems that cannot be neglected, such as electing the course and time of water adjustment, effectively handling the contradiction between water supply and water demand, utilizing the water resource rationally and high-efficiently and so on. Especially, excessively exploiting groundwater and chasing short-term interests are aggravating to some extent owing to water resource shortage and the function of market economy. As a result, the range of water table fluctuation expands and the public welfare ecological construction and development are greatly restricted. In the interleaved zones of desert and oasis, there are many unsuitable or degradation phenomena after water allocation, with a deterioration trend in eco-environment and agricultural yielding condition.
