Objective To get the current situation of STD/AIDS professional training nationwide and provide evidence for formulating guideline of professional training programme on STD/AIDS. Methods The training practice was investigated by mail and interview in December 1999. Results It was reported that 943 training courses had been held and 53 105 health care workers had been trained in 31 provinces during 1996-1999. There were some good experiences as well as problems.

Objective To get the current situation of STD/AIDS professional training nationwide and provide evidence for formulating guideline of professional training programme on STD/AIDS. Methods The training practice was investigated by mail and interview in December 1999. Results It was reported that 943 training courses had been held and 53 105 health care workers had been trained in 31 provinces during 1996-1999. There were some good experiences as well as problems. It was found that the coverage of training was limited (10%-20% estimated). Trainees were most personnel working on STD/AIDS. The contents of training focused mainly on clinical aspects and, the preventive aspects were always neglected. The main reasons affecting training were lack of funds, busy work and inadequate for national training materials and guideline. Conclusion It is necessary to provide policy support, sorting-orientated direction and strengthen training of trainers for national STD/AIDS professional training.

目的 为了解全国性病艾滋病专业培训现况,协助卫生部制定全国性病艾滋病专业培训指导方案。方法 于1999年12月对全国开展性病艾滋病专业培训现况及需求进行了函调和现场访谈。结果 收到31个省市1996~1999年举办943期培训班、培训53105人次的报告,反映出许多好的经验,但发现培训覆盖率较低(估计10%~20%)、培训对象多集中在性防专业人员、培训内容偏重临床,忽视预防;影响培训的主要原因是缺经费、工作安排不开以及要求编写国家级培训教材和教学大纲等。结论 加强全国培训需进一步提供政策支持、分类指导和加强师资队伍建设。

Ecological service is the base for ecosystem preservation and management, and establishment of rational compensation mechanism for resources management and use. It is also one of the important part of global economy. In this paper, the authors estimated the economic value of ecosystem services in natural forests, western Sichuan Province according to the statistical data of forest resources of Sichuan in 1995. The total value of ecosystems service of western Sichuan natural forests forest is estimated to be 46.84×10 8 USD/a, in which the ecological, economic and social values account for 77.51%,17.10% and 5.39% respectively. This presents obvious ecological function of natural forests in the area. In the ecological benefits, climate regulation, erosion control and deposit conservation, nutrient cycling and residues treatment have higher values. The ecosystem service value of natural forest in western Sichuan accounts for 0.52% of that of the whole country in China. In which climate regulation and genetic resource have high contribution to the whole countrywide level, accounting for 2.25% and 2.76%. This is only a conservative and lower estimation of ecological service of forest ecosystem in western Sichuan due to uncertainty and inaccuracy of methodology.

生态服务价值既是实施生态系统保育和管理、建立合理生态补偿机制的基础 ,也是全球经济的重要组成部分。作者根据四川省 1995年森林资源统计资料和其它有关文献 ,按照Costanza的生态服务功能系统初步估算了四川西部天然林生态系统的 17类生态服务价值。川西天然林生态服务功能总价值为 46 84× 10 8USD/a,其中生态效益、经济效益和社会效益分别占 77 5 1% ,17 10 %和 5 39% ,这反映了天然林生态系统具有极显著的生态功能。在生态效益方面 ,气体调节、侵蚀控制和层积物保持、养分循环、废弃物处理价值等生态功能尤其明显。川西天然林生态服务价值占全国总价值的 0 5 2 % ,但气体调节和遗传资源对全国生态服务功能的贡献很高 ,分别为 2 2 5 %和 2 76 %。由于天然林生态系统具有许多不确定性以及方法上的不成熟 ,因而本文得到的川西天然林生态服务价值只是一个保守的、较低的估计

Conventional Kalman filter(TTF) based on information fusion includes two methods—state vector fusion and measurement fusion. The conventional measurement has lower estimation error but a higher computational time. A kind of MTF model is provided which gives a better state estimation. An example is given to prove that this model has better performance and less computational time than the conventional method.

Kalman滤波是一种应用非常广泛的状态估计算法,基于信息融合的Kalman滤波包括状态向量融合和测量融合两种方法。传统的Kalman方法(TTF)具有较低的估计误差和很长的计算时间。提出的状态向量和测量向量的融合模型MTF利用局部融合信息给出一种更好的状态估计,计算时间短,性能也比TTF高。
