Abstract:
In this paper,on the basis of field investigation,and by using SPSS 18.0 mathematical statistics software,and adopting the combination of qualitative and quantitative method,the artificial Cypress funebris health evaluation index system was determined,including 4 categories such as structural,functional,adaptab environmental indicators and tolalling indicators.In the meantime,using principal component analysis method and analytic hierarchy process (ahp) with index weights,the forest health assessment was conducted on 126 wild samples in the upper hillside area.Results showed that the evaluation results of two methods were basially similar;the healthy and unhealthy stands occupied the vast majority (71.43% and 61.90%,respectively); the high quality stand was few in number,and the evaluation results of two methods were 6 and 9,respectively,occupying 4.76% and 7.14%.For upper hilly-gully regions' most artificial cedar forest,feasible forest management measures should be implemented to improve the level of management in order to get more ecological,economic and social comprehensive benefits of artificial Cypress funebris.

Abstract:
With the rapid development of the urbanization under the current situation,the urban wetland has become an important resource for urban ecological security.The development of urban ecological leisure based on urban wetlands plays the key role in urban quality improvement.Patch-corridor theory is the important guiding ideology for urban leisure planning and development,network construction and ecological protection.In the opinion of landscape ecology,patches gather crowd,material flow and information flow;on the other hand,the corridors deliver the same flows above.An integral urban leisure network includes numerous patches and corridors.All kinds of flows circulate in the leisure network smoothly.For an urban wetland leisure network,the combination of patches and corridors can promote the development of leisure scale and level.Wetland patches can be planned as recreational activities gathering place,and wetland corridors can be planned as leisure tourism route.Those wetland resources such as swamp (beach,peat lands),lakes (reservoirs) and ponds,rice paddies and other wetland patches,have particular leisure attraction and recreational activities space in cities.The urban wetland resources can be developed as a wide variety of special leisure attractions.Then,those leisure attractions will be important leisure nodes or essential urban recreation centers in the urban wetland leisure space network.Taking Meishan city's urban wetlands leisure tourism development for example,the actual application of patch-corridor theory in urban wetland recreation planning development and protection was demonstrated.The results have shown that river systems play important role in urban wetlands,an urban wetland network of the Minjiang River recreation zone,four urban wetland parks and Tongjiyan Weir historical culture leisure corridor have been built up for Meishan city.The ecological protection measures for wetlands are based on source-sink landscape pattern and wetland resource monitoring system.

Abstract:
In order to identify palatable base baits to confect poisonous baits,to control the damage of the red bellied squirrel in economic plantation,experiments were conducted on the palatability of three common baits (apples,carrots and corns) for the red bellied squirrels in laboratory.The results showed that in single-choice tests,the palatability index of apples to carrots and corns were 0.88 and 0.49,respectively.In multi-choice tests,the palatability index of apples to carrots and corns were 0.36 and 0.30,respectively.The palatability of apples was the best,followed by carrots and corns.Tests were also made on the palatability and deratization effect of bromadiolone and chemosterilant baits in different concentration.The results showed that palatability of all poisonous baits were good,and the palatability of bromadiolone baits was better than that of chemosterilant baits.0.01% bromadiolone baits and 1.00% chemosterilant baits would cause 100% mortality.The deratization effect of bromadiolone baits was better than that of chemosterilant baits after the first feeding,but the lethal time was longer.Taking palatability,killing rates and lethal time into account,the use of 0.01% bromadiolone apple baits and 1.00% chemosterilant apple baits were recommended to control the red bellied squirrels.

Abstract:
The investigation was conducted on the forest resources of State-owned Forest Reserve in Hega Town of Huidong County.It was found that main species in the Reserve were Huashan pine, Yunnan pine and fir.In the Reserve,pure forests were main,with a part of mixed forest of various species. Growth conditions and site conditions were analyzed. The research results showed that the growth of tree species was directly related with the regional natural conditions and soil factors.High temperature,and low rainfall would cause slow growth of trees.thus economic benefit and ecological benefit would significantly reduce.
