The study was conducted in Mangling Village under Dehong Perfecture, Yunnan Province, for thorough investigation of forest tenure structure, management mode and forestland transfer of collective forests as well as of farmers' preference for management and transfer intention. The impact factors of management orientation of farmer households were analyzed with Logistic Model. The results showed that tenure structure and management modes of collective forest have been diversified after the collective forest tenure reform, and 87.5% of farmer households preferred to independent or joint management while 12.5% of them would rather to transfer their forestland. The choice of farmer household for management mode was mainly influenced by their education background, production skill, household labors and household income sources. The main factors influencing farmer households' forestland transfer activities include the proportion of forestry revenues to the total revenues, farmers' experiences, amount of household labor and forest land area.

Ecological civilization, which refers to the harmonious development of man and the nature, has the connotation of the ecological material civilization, ecological consciousness civilization, ecological institutional civilization and ecological behavior civilization. The research on ecological civilization evaluation index system is important in that it can provide the guidance for the construction of ecological civilization, and besides it can improve public recognition of the importance of ecological civilization to the level that they will personally contribute to the development of ecological civilization. The paper attempts to set up an evaluation index system for ecological civilization construction based on consulting to relevant documents, in a bid to provide some policy references for relevant departments.

The establishment of China’s forestry science and technology evaluation system is an important guarantee measure to improve the level of forestry science and technology management and promote forestry science and technology advancement. Based on the analysis of the current condition of forestry science and technology evaluation in China, the paper presents the suggestions to establish and improve forestry science and technology system, including the change in evaluation subject, the standardization of evaluation approaches and the implementation of classified evaluation, to solve the problems existing in the current forestry science and technology evaluation like non-standardization of evaluation methods, incomplete evaluation system and unsound evaluation indicator system.

The shortage of forest tending funds in China has caused the retarded thinning for those forests that need urgently the tending thinning, which in turn has a negative impact on the implementation of forest management activities and results in the poor state of forest quality, function and healthy. This paper analyzed the necessity to implement forest tending subsidies, concluded the experience abroad, and proposed some policy recommendations on how to implement forest tending subsidies in China. It was indicated that forest tending subsidy policy should be fully implemented for a long time in China; the funds for forest tending subsidies should be obtained from multiple sources and multiple forms explored. The focus of the subsidy should be put on how to mobilize the enthusiasms of forest farms and forest farmers to engage in forest tending as well as on its ecological effects and livelihood benefits. At the same time, it is necessary to pay close attention to the problems propping up from forest products trade contributed to by the forest tending subsidies.

Climate is a dominant environmental factor in building ecosystem structure and driving biotic dynamics with topographic dependence on spatial distribution. This paper demonstrates the application of interpolation technique to describe spatial climate distribution. A digital elevation model (DEM) in resolution of 0.01 degree of latitude and longitude has been developed because the incorporation of spatial dependence on topography is crucial to accuracy of interpolation. Climate data from sparse and discr...

Inheritance of line Jinghe891-l resistant to pathotype of Puccinia striiformis in two patterns of temperature (Normal: day 18℃ /night 10℃ , High: day 24. /night 15℃ )was studied in this paper. The results showed that there were at least two pairs of dominant major genes and one pair of recessive minor genes in Jinghe 891-1. The two pairs of major genes that conferred resistance to CY31 were allelic or linked closely with resistance gene in Jubilejna Ⅱ , Kangyin655 and T. spelta Album. They were novel resistance genes and were inherited in a repeated or independent mode. The minor genes, which could modify the major genes, were sensitive to temperature and conferred resistance to all pathotypes of Puccinia striiformis in China. It is recommended that this line can be used as an important resource stock.

In recent decades, there has seen a dramatic expansion of global planted forest area and their great impact on human life. It is reported in Forest Resource Assessment 2010 that the current area of global planted forests is about 264.million ha, representing only 7% of the total forest area but able to meet the two thirds of the global demand for logs. Planted forests can not only provide timber, fiber, fuel and non-wood forest products, but also contribute to carbon sequestration, restoration of degraded land, landscape rehabilitation and watershed protection. Besides, planted forests can also provide the recreation and amusement for people. In such sense, in the coming decades, planted forests, driven by various factors such as social- economic conditions, market, consumers' demand and new technologies, will have good opportunities for development, and will also increase their contribution to achieving the series of development objectives worldwide. In the meanwhile, the development of planted forests is also constrained by the factors like policies, laws, regulations, technologies and funds, and therefore faced with the challenges in terms of eco- environment preservation, economic development and protection of community interests. Based on the long- term monitoring and research of planted forest development as well as the field study of planted forests abroad, the paper identified the opportunities and challenges in the development of global planted forests through such methods as the SWOT, policy analysis and the others, and proposed the policy choices for promoting the sustainable development of planted forests: 1) There is a need to further understand the functions of planted forests and the importance of the degraded land restoration; 2) A good institutional guarantee and investment environment should be created for the planted forest development; 3) The advanced concepts and methods in terms of the planted forests management should be actively promoted and
