The comprehensive value of the planted seedlings under forest in the designed scheme in Beijing were assessed by applying VE and VA methods. It was indicated that the value of the seedlings under ecological forests followed the order of Quercus variabilis, Broussonetia kazinoki, Cotinus coggygria, Acer truncatum etc. It was concluded that in the forestry management, comprehensive values should be considered to select seedling species with high values for regeneration under forests.

评价结果认为，在以生态公益林定位的森林经营中，人工林下更新幼苗的综合价值依次是栓皮栎、构树、黄栌、华北五角枫等，所以在林下层苗木的经营选择中应该按照这些树种的综合价值来进行苗木的选择和操作。

Nay, when time and leisure are wanting to add ample theoretical explanations to an extensive casuistical drill, we should not criticize him who would under these circumstances insist on the latter at the expense of the former; it is the more necessary in actual practice.

不仅如此，当时间和休闲是要补充充足的理论解释，以广泛casuistical演练中，我们不应该批评他的人会在这种情况下，坚持对后者牺牲前者，它是更需要在实践中操作。

In traditional experimental spectrum meters, the measurements, analyses, display and controls of them were separated, and made the experiments complexly operating.

在现在的实验光谱仪器中，光谱的测量、分析、显示和仪器的控制往往是分离的，这样使得在实验时操作繁琐，可观性不强。

With respect to the analysis, the operation of spam combination system in practice design and construction steps was summarized by some concretive case study. Finally, the future development of spam combination was explored in perspective.

最后在以上的分析基础上，结合建筑实例，总结跨越式联结体系在实际操作过程中的各构成元素之间关系的具体处理，探究其发展倾向。

This work contributed essentially to optimal planning of refinery management. A strategy for solving the decision problem of short—term refinery planning is proposed, that is, to obtain the real time information of unit operations and environmental conditions by means of computer simulation, to dynamically configurate and modify the decision model depending on both simulation and expert reasoning, to make decision analysis and short—term production plan with the aid of expert simulation system. In this paper, a new approach cellad ESDSS was proposed by integrating DSS and expert simulation system . As a case study of ESDSS, a so called RESDSS was constructed, which is composed of seven subsystems, namely: data base subsystem, model base subsystem, method base subsystem, knowledge base subsystem, experiment base subsystem, human computer interaction subsystem, and expert simulation executing subsystem. The main results and contributions of this work are as follows:(1) A novel approach of DSS named ESDSS was proposed, which integrates DSS and ESS.
