It showed that the niche breadth and niche overlapping indexes of the enclosed grassland in 2007 are much lower than in 2006 as a whole; The niche breadth of Artemisia ordosica is bigger than other species in the region in 2002. In 2003, the dominant species were Artemisia ordosica and Salsola ruthenica. Their niche breadth indexes were 0.544 and 0.460 respectively. The results of niche overlapping in 2006 and 2007 also showed that the species with big niche breadth didn't always have big niche overlapping, and the niche breadth and niche overlapping did not have a positive direct linear relation.
结果表明:2007年封育区植物种的生态位宽度及种间的生态位重叠指数总体上较2006年有所降低;2006年黑沙蒿生态位宽度最大,达0.768,是06年封育区的优势种;2007年封育区的优势种为刺沙蓬和黑沙蒿,其生态位宽度值分别为0.544、0.460;2006年和2007的生态位重叠结果均表明,生态位宽度大的物种不一定和其他物种有大的重叠指数,较高的生态位宽度和较高的生态位重叠之间并不存在直接的线性关系;2006年、2007年较高的Pianka生态位重叠指数都出现在生态位宽度较小的物种之间。

The disturbing rields caused by the speedup and quietude of upper crustal movement in Tibetan Plateau indicate that, when the upper crust movement is speedup in Tibetan Plateau and keeps the boundary condition unchanged, the energy stored in upper crust is released, the driving force by Indian plate increases the horizontal compression stress and movement in other layers in Tibetan Plateau, and increase the horizontal compression stress in the whole geosphere in North China area Comparing the disturbing distribution of horizontal compression stress in the upper mantle layer, the value in North China area is only about one twelfths of that in south part of Tibetan Plateau.

The analyzing aboved is made from earthquake's space distributing, periodicity, migration phenomenon, repetition, strength, frequency, b value etc., according to data of earthquake station net in Shaanxi Province and microseisms station net watching results in Xi'an area. 3 group faults which are NEE, NW and EW direction control earthquake activities in Guanzhong area. Epicenter depth mostly is 5-25km and in shallow-focus earthquake. Earthquake in east area of Guanzhong was stronger and weaker in the West in history. Fen-Wei earthquake belt showed more activity. Microseisms and small seisms is main movement in recent earthquake, it has 8-10years' period of movement and show the trend that they are strong in the West but weaker in the East. And frequency and biggest magnitude of earthquake is supplement each other. In next years earthquake frequency will lessen but strength enhance, about M4. It presumes there is earthquake climax period in Guanzhong area in 2040 and M5-6 earthquake is happened at that time.
本文在对关中地区区域构造及重磁异常特征的分析基础上,根据陕西省地震台网监测资料及西安地区微地震台网监测成果,从地震的空间分布特征、周期性、迁移现象、重复性、强度、频度、b值分析等方面,对区域地震活动特征、关中地区地震活动规律进行了分析研究,关中地区地震活动主要受北东—北东东向、北西向、东西向三组方向的断裂控制,震源深度多为5—25公里,均属浅源地震,历史地震表现为东强西弱,东部的汾渭地震带表现出较强的地震活动性,近代地震活动主要以微震或小震为主,存在着8—10年的活动周期,近期表现出西强东弱的趋势,地震的频度与地震最大震级呈互补关系,未来的几年间,地震频度会有所减少,强度会增大,将有可能发生4级左右的地震,推测在2040年左右,关中地区将进入地震高潮期,届时将可能有5—6级左右的地震发生。

DI is the most ideal irrigation indicator as it is very much influenced by soil water potential and less affected by meteorological factors. DI value of zero is probably the best irrigation threshold. MDS is strongly affected by meteorological factors and requires reference MDS under well-irrigated conditions. RT on the other hand is not significantly related with soil water potential. Therefore neither of these variables is suitable as irrigation index.
DI 受土壤水势影响产生变化的趋势明显并受气象因子影响较小,是最理想的灌溉控制指标,可将 DI =0作为灌溉控制临界值; MDS 受气象因子影响强烈,变异性较大,且需要充分灌溉条件下的 DI 作为参考, RT 与土壤水势的相关性不高,因此均不适合单独作为灌溉控制指标。

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 show that methyl group strengthens the electrostatic attractions, but reduces the H-bonds effect, while benzyl group can make both electrostatic and H-bond effects strong. The theoretical results are identical with the results of the collectors flotation tests. Collecting ability of the quaternary amine salts is better than that of dodecylamine and dodecyl bimethyl amine. The quaternary amine salt containing benzyl group performs best, and it is little affected by pH value. Substitution of N-containing polar group in amine collectors can impact the aluminosulicate minerals flotation.
研究结果表明:甲基的取代可增强阳离子的静电作用能力,同时,削弱它与矿物表面之间的氢键作用;苄基的取代不仅增强药剂的静电效应,而且增加氢键的结合能力;理论分析结果与浮选试验结果一致,季铵盐的浮选能力较伯胺与叔胺的强,连有苄基的季铵盐对铝硅酸盐矿物的捕收能力最强,且受pH值影响小。
