- 环鄱阳湖地区休闲农业旅游发展研究
- 作者： 冯安峰 王燕华 来源：景观研究(英文版) 年份：2010 文献类型 ：期刊 关键词： Suggestions The area agriculture Leisure and countermeasures Poyang Lake around
- 描述：Leisure agriculture tourism is the combination of agriculture and tourism,which is an important part of the new rural construction.The area around Poyang Lake is rich in flora and fauna,landscape,agricultural and fishing products,folk and other natural and cultural resources,so it has good infrastructure of leisure agriculture tourism.Under the background of the formal approval of "Planning of eco-economical region in the area of Poyang Lake in Jiangxi Province" by the State Council,which aims to escalate the constructing of Poyang Lake from eco-economical region to national strategic policy,leisure agriculture tourism in the area around Poyang Lake has broad development prospects.This paper discussed the advantages,and disadvantages of the development and management of leisure agriculture tourism in the area around Poyang Lake,and also put forward some suggestions and countermeasures.

- 描述：Since the construction of the Three Gorges Dam,the Poyang Lake hydrological characteristics obviously changed.During the impoundment period of the Three Gorges Reservoir,the hydrodynamic factors of Poyang Lake varied.Water level dropped,the velocity decreased and water exchange time lengthened,which changed the release of phosphorous from sediments.In order to investigate how the hydrodynamic factors influence the release of phosphorous from sediments,we used a two-way annular flume device to simulate the release characteristics of phosphorous from sediments under variable water levels and velocities.We found that both water level rising and velocity increasing could enhance the disturbance intensity to sediments,which caused the increase of suspended solids(SS)concentration,total phosphorus(TP)concentration in the overlying water,and the ability that phosphorus released to overlying water from sediments enhanced as well:when overlying water velocity maintained 0.3 m/s,SS concentration increased to 4035.85 mg/L at the water level25 cm which was about 25 times compared to the minimum value and TP concentration in the overlying water also reached the maximum value at the water level 25 cm which was 1.2times that of the value at 10 cm;when water level maintained 15 cm,SS concentration increased to 4363.35 mg/L at the velocity of 0.5 m/s which was about 28 times compared to the value of 0 m/s,and TP concentration in the overlying water increased from 0.11 mg/L to 0.44mg/L.When the water level maintained 15 cm,the phosphorous release rate reached the maximum value of 4.86 mg/(md)at 0.4 m/s.The concentration of total dissolved phosphorous(TDP)and soluble reactive phosphate(SRP)both in overlying water and sediment-water interface were negatively correlated with p H.Using the parabolic equation,the optimum water level at a velocity of 0.3 m/s was calculated to be 0.57 cm,and the optimum velocity at water level of 15 cm was found to be 0.2 m/s.
