The germplasm resources of bamboos is very rich in Yunnan. Though the reaserch of bamboo diversity conservation is just beginning today, the in situ conservation, developing nature reserve, and ex situ conservation, setting up bamboos garden, have got a great achievement. The period of bamboo flowering is longer and the fruitification rate is lower, so the Collestion of seeds is difficulty. The flowering, fruitting of some bamboos and its seeds collectiong, storage and utilization are introduced in this paper. © (2014) Trans Tech Publications, Switzerland.

Dendrocalamus sinicus is an endemic species in southwestern Yunnan, China, and it is the the largest bamboo in the world. It can grow to more than 30m tall with 30cm in diameter. Its culms yield per unit area is 5-8 times as that of Phyllostachys pubscens that is now popularized as a major economic bamboo species in China. So it is one of the most excellent economic bamboo species in south China and in the tropical and subtropical areas of the world. Based On the investigation of the biological characteristics and present seed resources situation of Dendrocalamus sinicus, the paper discusses the limitations of its natural population distribution, its fragile growth and propagation, and its rich meaning in culture. The authors suggest that this species be included in the list of wild plants for priority protection in China, nature reserve of Dendrocalamus sinicus (ecological and cultural) be established in its main distribution areas and that its scientific protection and industrial development be carried out as soon as possible. © (2014) Trans Tech Publications, Switzerland.

A new species of Gesneriaceae, Ancylostemon dimorphosepalus W.H. Chen & Y.M. Shui, is described and illustrated. It is characterized by its cordate leaves, purple flowers, dimorphous sepals, and small upper lobes of the corolla. Its relationships with the similar species, Ancylostemon aureus and Oreocharis rotundifolia, are discussed. © Finnish Zoological and Botanical Publishing Board 2012.

The long-term dynamic changes of the values for ecological service function of Pinus kesiya forest in China since 1987 had been studied. The results suggested that the area of Pinus kesiya had decreased and its value for ecological service function had also decreased from 365.1 × 108 yuan per year to 313.50 × 108 yuan per year from 1987 to 2002. Afterward, the value increased to 328.39 × 108 yuan per year at 2007 with the regeneration of Pinus kesiya forest. The value for ecological service function of Pinus kesiya per unit area had increased during the past 20 years from per hectare 5.44 × 104 yuan per year in 1987 to 5.56 × 104 yuan per year in 2007,and the average annual increase is 0.11%. Generally, the value showed strong positive correlation with the increasing per unit stock volume of Pinus kesiya, which indicated that the service value will increase with the improving of stand quality.

Using the data of the fifth continuous forest inventory of Yunnan province, and based on ecological function analysis methods, the authors assessed the ecosystem services values of forests in Yunnan province. The total value of ecosystem services was 12 353. 80 × 108 yuan per year, in which the indirect product value was 12 224. 36 × 108 yuan per year, accounting for 98.95% of the total, the product value was 129.44 × 108 yuan per year, accounting for 1.05%. The ecosystem service value was 94.41 times of product value. The forest area and ecosystem value in Yunnan province account for 10. 02% and 12. 21% of China' s total. The ecosystem service per hectare of forest in Yunnan was 6.77 × 104 yuan per year, which was higher than the average value of China (5. 52 × 10 4 yuan per year).

Due to the special geographical position and the diversified habitats, there are rich Bamboo Resources in Yunnan, and Yunnan is one of the areas in the world with the most abundant bamboo species, ecological types, and natural bamboo forests. In this paper, the bamboo resources, bamboo industry and sustainable development of Yunnan are systematically studied. © (2014) Trans Tech Publications, Switzerland.
