The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.

结果表明，在烟株生长前中期，当施钾量达到180 kg/hm2以上时，株高增长显著变慢，而定型株高则显著增高；茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平，叶面积指数也存在显著差异；单位面积产量和产值以施用180 kg/hm2的处理居首位，中上等烟比例和均价以施用225kg/hm2的处理最高，这两种处理的以上4个经济性状与CK之间存在极显著性差异；烟叶中的总糖和K2O含量随施钾量的增加而上升，烟碱、总氮、蛋白质和C-含量则下降；缺钾症状随施钾量增加而减轻，至施用180kg/hm2时已无缺钾症状；烟叶气候斑的发生程度也随施钾水平的提高而减轻。

The Shannon-Wiener index and Simpson index of lichens on trucks at 0– 2.0 m height were 2.71 and 0.89 for the oak coppice, 2.43– 2.45 and 0.88– 0.89 for the secondary P. bonatii forest and Z. bungeanum plantation, and 1.25 and 0.67 for the primary forest, respectively.

To build the index system for the evaluation, 3 main indexes and 12 relative factors were selected in the steps of organization, scheme and execution. Terfel Method was adopted to quantize indexes and factors, and exponential sum method was used to calculate the success degree of factors, indexes and the whole project.

The main results are shown as follows:1.Screening freezing tolerant cultivars and lines of chrysanthemumTwenty seven lines of chrysanthemum grown outdoors were screened using \'injury rate\' and \'injury index\'.There were 7 cultivars and lines,which were relatively high tolerant to freezing treatment,i.e.,\'Jinbuhuan\',\'Xuetao\',\'Fuli\',\'Donglin 4\',\'Donglin 6\',\'Donglin 9\', and \'Donglin 13\'.There were 3 cultivars and lines,which were less tolerant,i.e.,\'Fenmeigui\', \'Donglin 1\',and \'Donglin 2\';The determination of electrolyte leakage,and contents of free proline,MDA,CAT,fructose,glucose and soluble sugars on 7 lines of chrysanthemums at different stages freezing showed that \'Xuetao\' and \'Donglin 4\' were more tolerant than others, and that especially \'Donglin 4\' was able to regulate its osmotic pathway to alleviate the \'injury degree\' caused by freezing conditions.2.Protein expression profile of chrysanthemum under low temperature stressTwo-dimensional liquid chromatography was applied to fractionate and analyze total protein taken from \'Donglin 4\' leaves grown at low temperature and at normal condition. Chromatography peaks of fraction were transformed to gel graph by ProteoVue software.

主要研究结果如下：1、露地菊抗冻品种和品系的筛选利用受伤率和伤害指数两项指标对27个露地菊品系进行耐低温筛选，筛选出'金不换\'、'雪涛\'、'富丽\'、'东林4号\'、'东林6号\'、'东林9号\'、'东林13号\'等7个耐低温品系，同时发现'粉玫瑰\'、'东林1号\'、'东林2号\'三个品系的耐低温能力最差；通过对不同自然低温处理时期，7个品系的电导率、丙二醛含量、脯氨酸含量、过氧化氢酶、果糖、葡萄糖和可溶性糖等指标的测定发现，'雪涛\'和'东林4号\'的耐低温能力要强于其它品系，尤其是'东林4号\'对低温的调节能力较强，在低温胁迫下，能够调节渗透途径减轻低温的伤害。2、低温胁迫下，露地菊蛋白质表达谱分析利用二维液相色谱技术，分离了'东林4号\'露地菊品系的低温处理和对照样品的总蛋白，通过ProteoVue软件分析发现：处理样品与对照相比共有蛋白差异点36个，其中显著增强表达的蛋白差异点有26个。

Small town hearts of the New Year Brought down by gravity, crystal clear City fog and brave dialogue converge on the frontier Make haste, I feel your heartbeat With new taste for speed, out on the street Find a road to a humble abode where both of our routes meet The silver sound is all around and the colors fall like snow The feeling of letting go, I guess we'll never know Cheer up and dry your damp eyes and tell me when it rains And I'll blend up that rainbow above you and shoot it through your veins Cuz your heart has a lack of color and we should've known That we'd grow up sooner or later cuz we wasted all our free time alone Your nerves gather with the altitude Exhale the stress so you don't come unglued Somewhere there is a happy affair, a ghost of a good mood Wide eyed, panic on the getaway The high tide could take me so far away VCR's and motorcars unite on the Seventh Day A popular gauge will measure the rage of the new Post-Modern Age Cuz somewhere along the line all the decades align We were the crashing whitecaps On the ocean And what lovely seaside holiday, away A palm tree in Christmas lights My emotion Struck a sparkling tone like a xylophone As we spent the day alone Cheer up and dry your damp eyes and tell me when it rains And I'll blend up that rainbow above you and shoot it through your veins Cuz your heart has a lack of color and we should've known That we'd grow up sooner or later cuz we wasted all our free time alone

Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.

结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8%和13.7%，比不施肥提高27.6%和24.5%；冠层14~17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。

The results are as follows: 1 great changes have taken place in land use and landscape pattern from 1995 to 2000; the area of woodland, water and unused land has been reduced and that of grassland, cropland and construction land increased; 2 the advance of fractal dimensions, the diversity index and landscape fragmentation degree showed that landscape units became strongly fragmented; 3 the dominant degree of construction and unused land has changed little but that of meadow and water increased, and that of farmland and woodland decreased to some extent, which indicated that the trend of landscape pattern changed from cropland and woodland to meadow and water; 4 the changes of land use and landscape patterns near the road are obvious and it is urgent to strengthen eco_environment protection.
