建立健全天保工程区森林资源管护长效机制

实施天保工程的最终目的,就是使新疆的天然林资源休养生息,最大限度地增加林木蓄积,扩大森林面积,改善林分结构,保护物种多样性。发挥森林涵养水源,调节气候,保持水土,维护陆地生态平衡的效益,为新疆的经济社会可持续发展提供生态保障。1998年试点、2000年正式启动的天然林资源保护工程,在新疆29个工程区实施。经过不断的探索和努力,已经取得了一定成绩,继木材减产、富余人员一次性安置、减免森工贷款负债、实施分山头地块责任到人的管护责任制等措施之后,又决定自2005年起,全面停止天然林木材生产,并落实了停伐补助,使“坚持生态效益第一”…

Strategies on natural forest protection of collective forest area in minority nationality community in China

In the recent 20 years, it is a trend that forest will be distributed to villagers to manage in the world. Also in China, “forestry three determinations” has been carried out since 1980, and many new forestry devolutions have been put forward to and come into being. To face the fact of overusing up natural forest to result in the deterioration of ecology environment, the strategy of natural forest protection project (NFPP) is raised after the heavy flood in 1998. Now, it is paid close attention to systematically study to carry out the strategies of NFPP in collective forest area, especially in the community of minority nationalities. Based on the case of forest resource management in Datu Miao Village, the experience of its forest management in the past is analyzed and the strategies of NFPP in collective forest area are put forward.

太行山区天然次生林碳储量的研究

对太行山区天然次生林的碳储量进行了估算。结果表明:太行山区天然次生林的年净固碳量为27.62 ×105t,碳储量为361.45×105 t,这些碳折合固定CO2量1325.32×105t,同时放出O2为262.87×105 t。由此可见,太行山天然次生林在维持大气中O2和CO2平衡、调节气候、净化空气等方面起着相当重要的作用。

Sustainability assessment for Yanbian forest region, Jilin Province, Northeast China, based on ecological footprint model

Ecological footprint (EF) is one of the most important indicators in assessing the status and capacity of sustainable development. In this paper, the EF of Yanbian forest region, Jilin Province, Northeast China, was calculated and analyzed by statistical yearbooks and forest yearbooks from 1996 to 2002. Results showed that the EF per capita decreased, ecological carrying capacity (ECC) per capita almost kept a static status, and ecological surplus per capita increased year after year. The EF per 10 thousand Yuan GDP per capita in Yanbian decreased from 1996 to 2002. This trend was similar to that in western China, and distinctly higher than that in eastern China. The forest EF per capita kept a steady status, while the forest production footprint (FPF) and forest export footprint (FEF) decreased. Comparing the two years before and after the implementation of Natural Forest Protection Program (NFPP) with the five years, the mean va1ue of FPF and FEF reduced by 0.341 (46.32%) and 0.327 hm² per capita (54.94%), respectively. In conclusion, the regional and forest development in Yanbian was sustainable, and the implementation of NFPP was favorable to improving sustainable development of forest region. However, the sustainability capacity was still lower than those in forest developed countries. Therefore, it is very necessary to improve forest productivity, resource use efficiency and management of forest ecosystems scientifically. __________ Translated from Chinese Journal of Ecology, 2006, 25(2): 129–134 [译自: 生态学杂志]

A national forest resources assessment for Costa Rica based on low intensity sampling

A goal of a National Forest Inventory (NFI) is the provision of information which is relevant and required for national level decision making and monitoring in forestry, but also for related sectors.

This paper presents and discusses a pilot study from Costa Rica where in 2000/2001 a low intensity sampling approach was used to generate national level forestry information. On a 15 km × 15 km grid air photo plots were interpreted for forest and land cover type. Readily available 1997 aerial photographs were used that were, however, only available for about 70% of the country: of the 228 grid points for the whole country only 159 could be aerial photo interpreted. Out of the 15 km × 15 km base grid of sample points, a 2 × 3 subset was selected for field assessment, resulting in a sample of 40 cluster plots, each comprising of four elongated rectangular sub-plots of 150 m × 20 m located on the perimeter of a square of 500 m side length.

Two novel components were integrated into the inventory: (1) the field plots were established on all lands, so that the tree resource was not only tallied inside forests but also on all other tree-bearing lands outside forests. (2) In addition to the biophysical information gathered on the traditional field plots, interviews were carried out with forest owners on the site of the field plots, in order to obtain data on the use of the forest resource.

Field work was carried out by 6 field crews and took altogether about 3 months. Results were generated from the field samples for the entire country. Aerial photo based area estimates were compared to the corresponding estimations from field sampling for the same area. According to the field sampling the forest cover for Costa Rica in 2001 is estimated to be 48.4% (simple standard error percent 9.3%). An estimated 8.2% of the total volume (dbh > 30 cm, all species) is outside forest.

This inventory took place with support from Food and Agriculture Organization (FAO) in the framework of FAO–Forest Resources Assessment's (FRA) Program Support to National Forest Assessments; it was carried out jointly by Sistema Nacional de Áreas de Conservación (SINAC), the Costa Rican authority responsible for forestry issues, and Centro Agronómico de Investigación y Enseñanza (CATIE), an international agricultural research center. Experiences of the study were subsequently used to implement similar inventories in three more countries (Guatemala, Cameroon, The Philippines).
