利用遥感影像数据对黔东低山丘陵区1995～2.00年的景观格局与动态进行分析。结果显示,研究地区的景观破碎化程度呈上升趋势,多样性降低,景观均匀度降低,优势度增加,蔓延度降低,表现斑块形状变化的分维数指标均有下降,反映出斑块形状的不规则程度降低。研究区以林地、耕地和荒草地3种景观生态类型占据主导地位,已控制着区域景观生态格局及其发展。但耕地、林地、草地这三者之间相互转化比较频繁,说明退耕还林还草与毁林毁草开荒同时并存,植被恢复与退化并存,整体景观尚处于一种波动状态。研究区景观格局特征是岩性、地貌和人为活动共同作用的结果。

WE expanded Decomposition-Denitrification （DNDC）modeling study to systematically assess the potential effect of farming practice on N2./sub>O emission by choosing a corn-rape rotation and a soybean-winterwheat rotation field in guizhou Province, westsouthern china, asN2./sub>O emission from subtropical agricultural soil study plots. These sensitivity studies address questions relevant to issue of how change in fanning practice might be used to mitigate emissions. Manure additions had the most pronounced impact on N2./sub>O emissions of farming practice simulatedand the influence of manure addition was nonlinear （fig. 1）. This result is consistent with previous studies for an Iowa corn field. The addition of manure remarkably elevates the level of organic carbon, enhances soil nitrogen mineralization, and increases the efficiency of N2./sub>O production. Simulated results alsoshowed that the influence of manure additions on N2./sub>O emission from soybean-winter wheat field had

Some Interesting Results about Splitting

2.10 Third International Conference on Education Technology and Training (ETT 2.10)

作者： Maonian Wu college of science {2. University guiyang {2. Province china

logic programming, a primary means for repre- senting and reasoning about knowledge, has been applying in many domains. For instance, representing and Managing about Information Technology ＆ Engineering and knowledge. It is complex to compute the answer set of a logic programming. In order to decrease the task of computation, researchers naturally divide a big problem into many independent small problems. One useful method is splitting technology in logic programming proposed by Lifschitz. We show in this paper some interesting algebraic properties of splitting over logic programming.

THE Wengfu phosphorite deposit, a superlarge ore deposit, is located in the counties of Weng an andFuquan, Central guizhou, china. The deposit has been considered as typical sedimentary one since itwas found, but our new approach suggests that its formation be related to contemporaneous submarine hydrothermal activity. The Wengfu phospohorite deposit, belonging to Doushantuo stage of Late Sinian （Latest Precambrian）, was divided into two ore layers intercalated by dolomites and siliceous rocks. In the phosphoritesthere exist abundant fossils, including newly found "Weng an Biota" which contain the fossils of multicellular thallophytes as well as animal embryos and sponges. Besides the common sedimentary structures, the phosphorites and the coexisting siliceous rocks alsopossess obvious hydrothermal sedimentation features, which are presented as the following: （i） The coexisting cherts are, lenticular in distribution and with high SiO2./sub> purity and high homogeneous temperatures （up to 150℃） of the inclusions, characterized by hydrothermal sedimentation. （ii） The special "pellets" or "pisolites" formed by hydrothermal eruption are common in the phos-

An effective evolutionary method for solving the structural topology design problems of heat conductive fields is presented in this *** topology optimization model based on minimizing the heat transport potential capacity dissipation of heat conductive field is then established and the corresponding sensitivity of objective function is derived to determine which elements would be removed of the heat conductive field for having the increment of the objective heat transport potential capacity dissipation minimized.A Filtering technique is employed in sensitivity field to eliminate numerical instabilities in the evolutionary procedure. Numerical examples are presented to demonstrate the validity and the engineering applicability of the evolutionary method by con- trast with SIMP method,meanwhile we can come to a conclusion that higher speed of convergence and clearer optimal topology dis- tribution without intermediate elements can be attained by using evolutionary strategy,with the results laying a reliable foundation for the subsequent shape and size optimizations in thermal engineering.
