The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.

摘要运用样方法对贵州省玉舍国家级森林公园稀有保护植物十齿花群落的物种多样性进行了研究，结果表明：玉舍国家级森林公园十齿花群落以蔷薇科、杜鹃花科、壳斗科、桦木科、山茶科、樟科、忍冬科、山茱萸科等为优势科；10个样地中有8个样地以十齿花种群占绝对优势，其平均重要值高达135.69，远远高于其它种群；十齿花群落乔木层物种丰富度为2.847、Simpson指数为0.601、Shannon-Wiener指数为1.523、种间相遇机率为0.601、均匀度指数为0.569，总体上均小于灌木层(分别为：5.580、0.830、2.377、0.829、0.672)，表现为较明显的亚热带常绿落叶阔叶混交林的物种多样性特征。10个样地中，Q1的物种多样性程度最高，Q3次之，Q5和Q6最小，多样性程度最低，10个样地的物种多样性排序为Q1＞Q3＞Q9＞Q7＞Q2＞Q4＞Q10＞Q8＞Q5＞Q6。

According to petrographic facies test, gravel sample mainly consists of quartz, albite, dolomite, and minor biotite; and sand sample is mainly made up of quartz and albite. As an important ASR active mineral, chalcedonite exists in fractures of dolomite and in matrix of cherty limestone. In rapid mortar bar test, expansion of sand, small gravel and middle gravel at 14 day are less than 0.1%, but keep increasing in long term.

岩相法检测显示卵石样品主要由石英、钠长石及白云石和少量云母类矿物组成，砂样品主要由石英、钠长石等矿物组成，重要的碱活性物质玉髓主要出现在白云岩裂隙和硅质灰岩的基质中；&砂浆棒快速法&检测结果显示砂、小石、中石样品14天的膨胀率均不超过0.1％，为非碱－硅酸反应活性骨料，但卵石样品仍具有一定的碱活性，且后期膨胀率一直持续增长。

Cooperating the advantages of SVM solve classification problems about small sample set, non-linear and multi-dimension model identification, I use SVM to train the sample set of different frequency signal and look for a super plane to divide the data into two parts. This method gets rid of complex computation which is a flaw of traditional decoding method.This paper introduces the theory and algorithm of SVM at first. It proposes to use the SVM to decode FSK signal based on the classifiable character of SVM.

结合支持向量机在解决小样本、非线性及高维模式识别问题中表现出的许多特有优势，运用支持向量机对不同频率信号的数据样本集进行训练，通过寻找最优超平面来对不同频率信号的数据进行快速分类，克服传统频移键控解码算法中需要进行大量运算的缺点，从而实现频移键控的解码。
