Natural forests were all destroyed. The main vegetation types are only Sophora davidii, Ostryopsis davidiana undershrub etc. and Hippophae rhamnoide, Populus simonii and Robinia pseudoacacia etc. built to restore the environment.

天然森林已全部遭受破坏，植被类型主要为零星分布的旱生小灌木狼牙刺、虎榛子等及以生态修复为目的的人工林沙棘、小叶杨、刺槐等。

Their structures were elucidated on the basis of chemical and spectral analysis. RESULTS: Twelve compounds were isolated from the 95% ethanol extract of the aerial parts of L.rotata. Their structures were identified as luteolin (1), luteolin 7-O-β-D-glucopyranoside (2), apigenin (3), apigenin 7-O-β-D-glucopyranoside (4), apigenin7-O-6-(E-p-coumaroyl-β-D-galactopyranoside (5), tricin (6), acacetin (7), genkwanin (8), lamiophlomiol A (9), lamiophlomiol B (10), shanzhiside methyl ester(11)and syringic acid (12), respectively.

结果：从独一味地上部分的乙醇提取物中分离得到了12个化合物，分别鉴定为木犀草素(1)、木犀草素7-O-β-D-吡喃葡萄糖苷(2)、芹菜素(3)、芹菜素7-O-β-D-吡喃葡萄糖苷(4)、芹菜素7-O-（6-反式－对－香豆酰基）－β-D-半乳糖苷(5)、小麦黄素(6)、刺槐素(7)、芜花素(8)、独一味素A(9)、独一味素B(10)、山桅苷甲酯(11)及丁香酸(12)。

Effects of ordinary silage and mixed silage on the Robinia pseudoacacia, Caragana and Amorpha fruticosa silage were studied by observing color, odor, texture, pH, organic acid composition and content, ammonia-N / total-N ratio, crude protein, neutral detergent fiber, acid detergent fiber and comparing their nutritive value before and after silaging. Results showed that silage quality of R.

对刺槐、柠条和紫穗槐进行了单独青贮和两两混合青贮，并从青贮饲料的色泽、气味、质地等感官品质，pH值、有机酸含量及组成、氨态氮／总氮比值这些发酵品质，以及粗蛋白、中性洗涤纤维和酸性洗涤纤维这些营养价值方面进行了分析评定。

Other species, such as Robinia pseudoacacia, Sophora japonica,Broussonetia papyrifera, Forsythia suspensa Vahl., Diospyros kaki, Koelreuteria paniculata and Amorpha fruticosa also have this kind of effect.

结果表明：树木对SO2有吸收累积的作用，但不同树种之间差异较大，其中绦柳净化SO2的能力最强，刺槐、国槐、构树、连翘、栾树、柿树、紫穗槐等树种也是优良的净化SO2污染的树种。

The average effective root density of Black Locust is as much as 45％ of Arborvitae's in the root roomalthough the distribution depth of Black Locust root is twice more than that of Arborvitae's in the same ages ofstand.

刺槐根系分布深度是侧柏的2倍多，但平均有效根长密度只有侧柏的44.5％。

In addition,the ideal working parameters were provided based on the research of working parameters and the object of pruning robot.During the research,a test system based on force sensor was developed,the friction coefficients between tyre and standing tree trunk of arborvitae,ginkgo and acacia were measured by the test system.This paper provides important data for the power selecting of pruning robot.

同时，对整枝机的工作参数、对象进行研究，提出了整枝机的合理工作参数，设计了一套测试系统；采用测力传感器测定整枝机系统轮胎与树木的作用力，计算出了轮胎与树木之间的摩擦系数；测定了侧柏、银杏、刺槐等几种主要树木的摩擦系数，为整枝机的动力选择提供了重要的依据。

Result Under the pretreatment conditions, the content of acetone extractives transformed. The hydroxyl and carboxyl, belonging to auxochromic groups, were oxidized into the carbonyl and ester groups. Also, there were plenty of auxochromic groups and chromophoric groups in the acetone extractives of silver chain.

结果］刺槐在预处理条件下，丙酮抽出物成分发生了变化，羟基、羧基等助色基团在预处理条件下氧化成羰基、酯基等发色基团，且丙酮抽出物的主要成分中含有大量发色基团和助色基团。

The hydroxyl and carboxyl, belonging to auxochromic groups, were oxidized into the carbonyl and ester groups, belonging to chromophoric groups, during inducing discoloration under the pretreatment conditions, which makes the wood color deeper. There were plenty of auxochromic groups and chromophoric groups in the acetone extractives of silver chain. The interaction between the auxochromic groups and the chromophoric groups made the wood color deeper.

结论］羟基、羧基等助色基团在预处理条件下氧化成羰基、酯基等发色基团，使木材的颜色加深；刺槐木材丙酮抽出物的主要成分中含有大量发色基团和助色基团，这些基团间的相互作用使木材颜色加深。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
