The natural resources and the ecosystem service functions are the basis for sustainable development of tourism.However,the tourism may probably destroy them if the natural resources are not well preserved.Consequently,it is very necessary to appraise the importance for tourism development.The paper takes Poyang wetlands,the largest freshwater lake in China as a sample based on the 3S and the theory of ecological function zoning.The result shows that there are plenty of resources for tourism development in Poyang wetlands.Because of the dissimilarity of geographical space and the diversity of natural ecosystem,there is a different suitability for ecological tourism in different areas in Poyang wetlands.The most suitable area for tourism is located in the Jinxian county,Poyang county and Xingzi county,and the total area is about 1 300km²,almost one third of the area in Poyang wetlands.The three counties have their own individual advantages and challenges in tourism development.Jinxian county is located in Nanchang city,the capital of Jiangxi Province,its geographical location is good for developing tourism.Poyang county has plenty of tourism resources and the national wetland park in it has developed for a long time,and Xingzi county is near Lushan with well-known tourism landscape in China.Therefore,it is necessary to make scientific planning and optimize the industry contents for sustainable tourism development.

To study the effect of different container sizes on the seedling raising of Quecrus variabilis and growth condition after afforestation,we use single factor randomized block design completely.The results suggest that container size A has greater influence on the seedling raising of Quecrus variabilis and growth condition after afforestation.The specific indicators of A are as follows:height is 36 cm,diameter is 6.4 cm,volume is 983 cm³,the form is deep cone.The seedling growth is the best in container size A.The height and ground diameter of Quecrus variabilis in the container are 47.9cm and 4.23cm.The Quecrus variabilis has good performance after afforestation and its survival rate reaches 100%.After afforestation the height and ground diameter of Quecrus variabilis are 63.5cm and 6.64cm,and it performs well on photosynthetic characteristics.Therefore,treatment A is the best choice for seedling raising and afforestation of Quecrus variabilis,in other words,the increase of the container volume and the depth can improve the growth of seedlings.
