一年生的

Dependent on the past research in seaice, in Bohai Sea, in 2003-2004 winter and 2004-2005 winter with level ice for the target we open the field experiments to study the essential spectrum characteristic of ice, removing by testing means various nonessential factor for sea water in the fixing big ice plate, building up 170 growth conditions to look like under the natural condition, the growth expect different sample series; in 2004-2005 winter and 2005-2006 winter continue two pass to break thorough Bohai Sea in the ship to collect 59 sea ice sample that have the non-essential ice factors in winter, open the influence research that the field hangs sand to contribute to the spectrum of the ice body; in 2005-2006 winter, fast ice to open the field spectrum curves to coast and analytical research.

总结前人的研究成果和开展一系列的室内实验，在渤海—北半球纬度最低的结冰海域，于2003/2004、2004/2005 连续两个冬季以单层平整冰为目标开展实验研究一年生海冰的冰体本质光谱特征，在固定冰盘上以实验手段摒除各种光谱干扰因素，在自然条件下建立170 个生长条件近似、生长期不同的样本系列；于 2004/2005、2005/2006 连续两个冬季通过破冰船深入渤海采集59 个具有非冰体本质因素的海冰样本，开展悬沙对冰体反射光谱的影响研究；于2005/2006 冬季，针对沿岸固定冰开展光谱测量和分析研究。

This research was conducted in degraded rangeland at the southwestern edge of the Mu Us sandland, Yanchi county, Ningxia, the soil seedbank features and its relation to vegetation was analyzed using similarity analysis and ordination method, the results show that seeds within soil distribute mainly in 0~5 cm soil layer, less seeds in 6~15 cm soil layer in exclosed and non-exclosed rangeland, for seeds in exclosed soil, species richness and diversity index H are higher, while D is lower, exclosure measure, generally speaking, can increase plant species and amount of vegetation and seeds in soil, some annual plants, mesophytes and halophytes appears in the soil or surface.

以毛乌素沙地西南缘宁夏盐池县的退化草场为研究对象，采用相似性分析和排序方法对封育和未封育草场土壤种子库的特征及其与地上植被间关系进行了研究，结果表明无论封育区还是未封育区，土壤种子库中的种子主要分布于0~5cm的土层，6~15cm土层的种子数很少；封育区土壤种子库的物种丰富度大于未封育区，物种多样性则表现为H 值较大，而D值较小，总体上看封育措施可以提高地上植被和土壤中种子的种类和数量，一些一年生植物、中生植物和盐生植物开始出现在地面或土壤种子库中。

Result Among the 1st principal components, the positive weight value of chest diameter was greatest and it was the eigenvector with greatest influence on the 1st principal components. Among the 2nd principal components, the character loading value of leaf-lobed width and the positive weight values of angle between leafstalk and its branch and leaf-shape index were greater. Among the 3rd principal components, the positive weight values of leaf number, branch length, branch thickness and developed degree of crown size of 1 year old branches were greater.

结果］在第一主成分中，胸径的权重正值最大，是对第一主成分影响最大的特征向量；在第二主成分中，叶裂宽的特征负荷值较大、叶柄与着生枝夹角和计形指数的权重正值较大；在第三主成分中，一年生枝的叶数、枝长、枝粗和冠幅发达程度的权重正值较大。

Although the quantity of seedlings in fenced plot of site A was bigger than that in unfenced plot, the life form of seedling cohort became simplified and the diversity was reduced.

羊草样地围栏外实生苗的数量高于围栏内，但更多的是增加了糙隐子草和牲畜不喜食的短命一年生植物的数量，减少的却是多年生植物的种类和数量。

Results of grafting trial shows: the budding survival rate on hybrid UCB-I was higher commonly than that on the Pistacia atlantica Desf; On two rootstocks, one-year-old branch performed better than twoyear-old stem; In mid August, the highest budding survival rate was attained with two rootstocks; After treatment with 50、100ppm IBA and 50ppm 6-BA, the budding survival rate on hybrid UCB-I was decreased, but the budding survival rate on Pistacia atlantica was increased evidently, particularly it has been increased 22. 8％ by treatment of 100ppm IBA.

阿月浑子嫁接试验结果表明：在杂种UCB-I上的芽接成活率普遍高于在大西洋黄连木上的芽接成活率；两种砧木一年生枝上的芽接成活率均高于二年生主干上的芽接成活率；8月中旬在两种砧木上的芽接成活率均最高；用50、100ppm IBA和50ppm 6-BA处理接芽后，均可显著提高大西洋黄连木上的芽接成活率，尤其100ppm IBA处理可提高其嫁接成活率22.8％，但上述处理都降低了在UCB-I上的芽接成活率。

Some annuals with good scents are sweet alyssum, the large flowering tobacco "Nicotiana Sylvestris", the Regal Lily, which flaunts clusters of trumpet-shaped white flowers, and velvety purple heliotrope.

The dominant species in the tree layer were found as Castanopsis chinensis, Endospermum chinense and Cryptocarga concinna . The Mesophanerophytes and Microphanerophytes were found having high percentage, and the Megaphanerop, Geophytes and Therophytes were notfound in the species life form spectrum of the community. The Mesophyll also had high Percentage in leaf-sizeclass spectrum of the community.

本群落以中、小高位芽植物占优势，缺乏大高位芽、隐芽和一年生植物叶型以中型叶为主群落的大部分优势种的种群分布格局是随机分布的优势种群的立木结构分析表明，本群落处于进展演替它与30a前比较有较大的变化乔木层原优势种黄桐、猴耳环、亮叶肉实等被锥粟、刺栲等替代。
