The crisis of fossil energy supply and the conditionof ecosystem deterioration have made the developed nations change their energy supply strategy from fossil to bioenergy. Development and utilization of bioenergy also afford a new way to solve problems of energy supply crisis and the environment pollution in our country. The cultivation of bioenergy forest is a system engineering, for all facets of it have to be considered as a whole, i.e. the cultivation of bioenergy forests,the development of biomass industries,the condition of bioenergy supply in China, research plan on bioenergy sci-technology, and policies encouraging bioenergy forest cultivation. Meanwhile, great afforts shall be made in dealing well with the relationship among biomass utilization and ecosystem conservation, multi-use of forests, sci-technology andbioenergy industry. And the relationship among the government, enterprises andforest managers in bioenergy shall be dealt with well to promote the healthy and fast dewelopment of bioenergy industries in P.R China.

Taking Haoping Protection Station (one of 4 stationsof this reserve)as an example, after describing present situation of animal andplant resources and the facts that they were damaged, this paper analyzed the main factors threatening animal and plant diversity of Taibai Mountain National Nature Reserve, such as overexploitation of resources by local communitydue to poverty, unsound management, permeation of commercial operation and overdevelopment of tourism programs with no suitable management. Additionally, considering concrete situations, this paper also presented some strategies for achieving sustainable development of this nature reserve, which were improving community residents’ living level, improving management and developing cautiously tourism programs in form of ecotourism. Strategies for sustainable development of nature reserve presented in this paper might shed some light on operationin other nature reserves in Qinling Mountains.

Data from 4 100m×100m natural forest plots,then uniform angle index and pair-correlation function are used to analyze the spatial patterns of trees in forest plots with varying areas. The result shows that thecorresponding tree spatial distribution patterns are related to plot areas. Patterns become stabilized with increasing plot areas, indicating that foreststructures should be analyzed with data from plots which are big enough. According to our study, 2500m² is appropriate for minimum plot areas.

This paper studies the development and biomass of undergrowth vegetations of young-age plantations, middle-age plantations and near-mature plantations of Cupressus funebris in Yichang suburb. The results show that,from young plantations and middle-aged plantations to near-mature plantations, number of arbor species,shrub species and herbaceous species increase to a different extent, but evergreen arbor nearly not increased. dominant species of shrub layer changed from strong-masculine to relatively neutral,dominant species of herb layer changed from carex brunnea and ficus tikoua to pteridophyte. Bad regeneration of Cupressus funebris had a distincteffect on the average height and cover of shrub layer and herb layer,which increasedon the whole,but average density descended a little. Biomass of herb layer and canopy floor increased,but as a result of bad regeneration of Cupressus funebris,biomass of shrub layer descended earlier,and increased afterward.

Based on field survey data, the regeneration characteristics of pinus tabulaeformis forest gaps in comparison with those tree speciesunder canopies was investigated. The result showed that(1)There are obvious difference in the quality and composition of the regeneration trees, species in gaps and under canopies inPinus tabulaeformis forest in Zi Wu Moutains, the important value of the Pinustabulaeformis under forest gaps is superior to that under canopies, which is the majorregeneration tree species in gaps. (2) There is better growth under forestgaps of seedlings and young trees of Pinus tabulaeformis. There are a few Pinustabulaeformis saplings above 7 years old under canopies,the number distribution of saplings above 1.0cm in collar diameter and above 50cm in height in gaps is superior that under canopies too. It shows that the survival rate of pinus tabulaeformis seedlings and saplings in gaps is superior to that under canopies with age increasing.(3)Variance analysis showes that the height variance of pinus tabulaeformis has obvious difference between forest gaps and canopies.(4)Relationship analysis shows there is anobvious and positive relationship between the Pinus tabulaeformis seedlings numbers and illumination intensity, but a negative relationship between this and vegetation coverage.

With the help of the relevant mathematical analysis approach,an investigation of dynamics of the forest resources based on the theoretical foundation of forest management was conducted withGIS used as a platform of system management. Its information sources come from data and digitalmaps of forest resources of Sanming City from 1996 to 2005. The result indicats that:the area of forest land of Sanming City has increased steadily. Althoughforest coverage rose and fell,it generally remained at a level of 76.8%. Thearea of the planted forests has increased,while the area of nature forests decreased year after year. The growing stock of standing timber has had a trend of increase since 1996. This study provids a scientific basis for drawing up policiesof sustainable development of forestry of Sanming City and a technologicalbasis as well and will be of a great value for promoting informationization ofthe management of forest resources.

The mangrove,especially the old tree population of Aviccenia marina in Techeng Isle,is one of the very precious coastal natural resources in China and highly significant both in their conservation and utilization. It is protected effectively through activities of recovering the old trees,improvement of the growing environments,gardening design and ecotourism,and itbecomes a new ecotourism site of Zhanjiang.The successful lab food products made of the fruits of Aviccenia marina from the Isle,Lan-Qian-Guo and Lan-Qian-Dou, show the potential double wins both in conservation and utilization of the coastal natural resources.

E.Dunnii is a fast growing and cold-tolerant speciesand its wood can be used for pulpwood and sawn timber. It is a species that is difficult for clonal propagation, but has also no blooming and fruit setting in many regions of Chinaand even 13-year old seed trees in orchards in Guangxi and Hunan have not produced seed. By now E.Dunnii seed must be imported with high costs, which haslimitedits development in China. 107 families of 15 provenances have been arranged inrandomly chosen block design. 30 families are selected primitively following the longitudinal growth of 11-months old, 52, 29, 35, 87, 94, 104, 86, 90, 76 and 101 are at the front of the 30 families ranking, and their average tree height is 2.17 meters. There are five elite provenances, namely17915, 17909. 17911, 17914 and 18758, their average tree height is 2.39 meters. The result of this experiment has provided the preliminary basis for the establishment of E.Dunnii seed orchard.
