By collecting ,testing, comparing, and analyzing the soil samples, soil recovery under the various recovery conditions along Mian CountyNingqiang highway was studied. The results were as follows herbaceous recovery to the soil fertility recovery in the prior was greater than the combination of grass and irrigation or than the pure bushes recovery. In each of them, the content of organic matter were 13.84, 7.50, 6.00 g·kg-1; In the recovery of herbaceous ecology, to grow leguminous plant and granminaceous plant together was better than pure graninaceous plant or pure leguminous plant. In each of them, the content of organic matter was 29.67, 17.51, 9.37 g·kg-1; to sow ryegrass and alfalfa together with some local grass seeds or to grow coxcomb, alfalfa and local couch grass together could bring better effects than to plant the alfalfa only. In each of them the increased organic matter contents were 4.93,17.51 and 9.37 g·kg-1;the quotas of the organic matter and alkaline hydrolysis nitrogen in soil fetility factor were closely connected, mainly because of the difference between the generation quantity and resolution quantity of the organic matter in the soil surface.

objective the effects of anthocyanin pigment from maize purple plant on resisting lipid peroxidation were investigated.methods the inhibition of anthocanin pigment from maize purple plant was examined in vitro that autcoxudation of lecithin liposome system induced by fe2+.50 mice were randomly divided into 5 groups.vehicle and different dose anthocyanin pigment from maize purple plant were given respectively,and then experimental injury of mice liver was induced to make use of bromobenzene and the content of mda was determined in liver homogenate.results the inhibition rates of anthocyanin pigment from maize purple plant on linoleic acid oxidation was higher that of ascorbic ascorbic acids.the content of mda in homogenate in middle and high dose of pigment were significantly lower than that in low dose and the injured control group.there were no significat differences in the content of mda in homogenate between low dose group and injury control group.conclusion the anthocyanin pigment from maize purple plant have the capability to resist lipid peroxide.

目的 探讨玉米紫色植株色素抗脂质过氧化的作用。方法体外实验测定玉米紫色植株花色苷色素在fe2+引发的卵磷脂脂质体体系中抗氧化活性。体内实验，取50只小鼠随机分成5组，分别给予溶媒和不同剂量的色素，然后采用溴代苯致实验性肝损伤，测定肝匀浆的丙二醛含量。结果在由fe2+引发的卵磷脂脂质体体系中玉米紫色植株色素对脂质过氧化有明显的抑制作用，抑制率随样品的浓度增高而增大，并且明显优于抗坏血酸。在溴代苯致小鼠实验性肝损伤模型实验中，中、高剂量组的丙二醛含量均低于损伤模型组。低剂量组和损伤模型组比较丙二醛含量差异无统计学意义。

The artifical fillers are hung under the plant floating bed then the remedial system combined by plant and microorganism came into being. The remedial effectiveness of the system was visibly better than that of the phytoremediation alone. So when the temperature is higher the remedial system combined by plant and microorganism is the preferable remedial technique to remedy contaminated water. In autumnal end and winterly outset, the temperature is lower, the plants begin to fade and die, and the plant must be harvested lest the relict of plant should contaminate water again. At the same time the technique combined by immobilized nitrogen cycling bacteria and microorganism which already existed in the water was used to remedy contaminated water.

将人工填料悬挂于植物浮床下，形成植物和微生物相结合的修复系统，其修复效果明显好于单独植物修复技术，因此温度较高时用植物和微生物共同结合的生物修复技术修复水体污染；秋末冬初温度较低时，植物开始死亡，必须将植物收割，以免植物残体造成二次污染，此时用固定化氮循环细菌和水体中原有微生物相结合的技术来修复水体的污染。
