查询词典 soil bank

The density of soil seed bank was 100~400 grain/ m2 and the seeds in upper layer (0~5cm) accounted for 58.2 %. The dominant species in soil seed bank included Cyperus rotundus, Lophatherum gracile, Boehmeria nivea., Cynodon dactylon, Digtaria sanguinalis and so on.

Otherwise, the predominant components in the seed bank are different from the subaerial predominant vegetation at correspond layer. The result showed that the growth of subaerial parts of plant community isn't obviously isochronous with the seed bank. So the inherent potential of soil seed bank has important influence on the regeneration of forest and the dynamic succession of plant community.

另外，种子库中优势成分与取样地点地面植被相应层次的优势种存在较大差异，说明植物群落地上部分的发育与其它地下部分的土壤种子库的发育具有明显的不同步性，这一结果表明土壤种子库的内在潜力对森林更新及植物群落演替动态产生了重要影响。

The soil bank may be summarized two type: colluvial deposit and accretion. The different original cause provide them different characters on colluvial deposit stability and stability under water.

由于其成因特点的不同，这两种岸坡在物质、地形地貌上有各自的特征，由此在稳定性和遇水再造方面的性质也表现出明显的不同。

通过在开孔的铰链式混凝土块铺面系统中种植香根草，其根系在基土中盘根错节，使基础土体成为土与草根的复合材料，草根可视为三维加筋材料，使土体强度提高；更有利于护岸防冲系统的稳定。

Vetiveria zizanioide is possesses strong depth roots and have better anchoring force and shear resistance; Vetiveria zizanioides is growed in ringent hinged joined concrete extending system,and its roots are interlaced and make foundation soil compound materals of soil and roots,but grass roots are considered three-dimensional reinforced materal and increase soil strength but also make for the stability of bank protection.

香根草具有纵深发达的根系系统，具有较高的锚固力和抗剪力。通过在开孔的铰链式混凝土块铺面系统中种植香根草，其根系在基土中盘根错节，使基础土体成为土与草根的复合材料，草根可视为三维加筋材料，使土体强度提高；更有利于护岸防冲系统的稳定。关键词：香根草，铰链式混凝土块，防冲护岸系统

In 1999, the Liaoning provincial important Sci-Tec started a key problem project for the technology of protecting and preventing of dangerous river bank and plain reservoirs. Under the support of this project, this research was carried out for experiment of engineering properties and bank engineering applications of geosynthetics. In order to solve the life and soil retention criteria of geosynthetics problems in bank engineering applications, the indoor tests, in-situ tests, locale antitypes tests and observations, theory analysis, and engineering examples analysis have been performed.

结合堤岸防护工程实际条件，采取室内试验、野外试验、工程现场原型试验或观测以及理论分析和大量工程实例验证分析的方法，对堤岸防护工程中应用的土工合成材料相关工程特性，尤其是老化规律和较大孔径织造布保土性准则，进行了较系统、深入的试验研究；在此基础上，通过典型工程实例及大量工程应用实践总结分析，重点对土工织物软体排、土工模袋、土工膜堤岸防护工程的设计方法和施工技术进行了研究。

Aimed at the increasing eco-environmental problems, including water shortage, water pollution, soil salinization, water loss and soil erosion, loss of function of the channel and river, biocenose degradation, etc, which severely infected the sustainable development for irrigation area, the main works in this paper are summarized as followed: constituting the measures of water resources shortages for developing agricultural water-saving technologies and adjusting agricultural structures; constructing the water polluting control and purification system of Mushroom lake: source control and decrement-sewage collection and treatment - channel ecological interception - wetland treatment -reservoir purification; putting forward the systematic projects for soil salinization and water loss and soil erosion of the integrated application of water conservancy agriculture and forestry.; constructing the ecological impervious channel model in west bank, from all of which theoretical bases and technical support for the eco-environmental rehabilitant in Manasi irrigation area were offered. All of these works were based on data collection, technical analysis, on-the-spot investigation, experimental research and technical development about Manasi irrigation area, etc.

通过对玛纳斯河灌区进行资料查阅收集、理论分析、现场勘察、试验研究和技术开发等途径，针对玛纳斯河灌区存在的水资源短缺、水体污染、土壤盐渍化、水土流失、沟渠河道功能缺失、生物群落退化等日益突出的严重影响灌区可持续发展的生态环境问题，制定了发展农业节水技术、调整农业结构的灌区水资源短缺的措施，构建了&源头控制减量-污水收集处理-引水调控-渠道生态截留-湿地生态处理-库区生态净化&的蘑菇湖水污染控制与净化系统；提出水利、农业、林业综合应用的灌区土壤盐渍化、水土流失问题的综合治理方案；构建了西岸大渠生态防渗型渠系模式，为玛纳斯河灌区生态环境修复建设提供了理论基础和技术支持。
