Research On Transformation Development And Spatial Planning Of Flood Storage And Detention Area In The Lower Yellow River

Flood disasters occur frequently in China.Since the founding of the people’s Republic of China,the Yangtze River,the Yellow River,the Huaihe River and other major rivers have experienced Basin wide floods and catastrophic floods.The flood storage and detention area has played an important role in reducing the flood peak and storing excess water at the critical moment of flood control and flood fighting,ensuring the safety of important flood control areas,and making great contributions to the task of flood control and disaster reduction in river basins.There are 97 flood storage and detention areas included in the national list of "Interim Measures for compensation in the use of flood storage and detention areas" in 2000(including 5 in the Yellow River Basin:beijindi,Dongping Lake,beizhankuan area,nanzhankuan area,Dagong).In 2008,a new round of flood control planning and adjustment of the basin retained the flood storage and detention area of Dongping Lake in the lower Yellow River,beijindi flood storage and detention area and nanzhankuan flood control protection area,and the rest were cancelled.In this paper,the research on the transformation development and spatial planning of the flood storage and detention area in the lower Yellow River is carried out.Because the function of flood storage and detention is still reserved in Dongping Lake and beijindi,the economic and social development is greatly limited.This paper studies the planning countermeasures in combination with the South widening area of the Yellow River(also known as reclamation widening area)which has the most development potential due to the cancellation of the function of flood storage and detention.Due to the influence of the function of flood storage and detention area and the policy of flood storage and detention area,the land use,people’s life,production and development activities in the flood storage and detention area in the lower Yellow River are greatly restricted.The economic and social level in the area is still in the 1970s,which is the poorest and backward region in Henan and Shandong.In order to completely change the unique poverty and backwardness situation of the flood storage and detention area,improve the people’s livelihood and improve the well-being of the people,this paper proposes a new model of efficient eco-economic development through the research on the transformation and development of the South expansion area,which is based on the establishment of sustainable land use structure,building a livable community and developing eco industry(including eco agriculture,eco forestry and eco industry)according to local conditions Tourism,etc.)to promote the establishment of an eco economic zone with prosperous economy and beautiful environment.In the summary of the development experience of the flood storage and detention area at home and abroad,combined with the current situation of the flood storage and detention area of the lower Yellow River and the planning of the South widening area,this paper studies the transformation and development mode of the lower Yellow River,and puts forward the planning Countermeasures of the South widening area to verify the feasibility of the transformation and development mode proposed by the author in this paper.This paper focuses on:1.Analyzing the necessity,urgency and feasibility of the transformation and development of the flood storage and detention area in the lower Yellow River and the South widening area;2.Proposing the influencing factors,development path and development mode of the transformation and development of the flood storage and detention area in the lower Yellow River,combining with the planning of the South widening area,proposing the planning countermeasures for the transformation and development;3.Designing the planning,policies and other institutional innovation and construction conducive to the transformation and development Discussion.
