自然声、人为声、历史文化声是声景设计中最常见的声音景观.通过分析声景观设计理念、功能及其存在的问题,并提出相应的应用策略,以期为声景观在园林设计中的应用提供参考.

居民日常生活质量高低的一大影响因素是园林景观工程雨水收集利用,建设质量高则能提升人们生活品质,因而该建设工程的合理设计和质量控制尤为重要,进而确保整个园林景观工程的建设质量.因此在园林景观工程设计中,必须进行多角度探究,在优化设计方案后,制定相应的措施有效控制质量,进而确保园林景观工程的优良品质,保证城市稳定基本发展.在我国经济不断发展、社会逐步推进的过程中,城市园林景观等基础设施的建设不断发展.人们生活品质受到园林景观中雨水收集利用的影响,该工程设计质量越高、设计越合理,越能给人们提供生活便利,同时越能有效处理污水,减少环境污染.

近年来随着城市化进程的加快，各地居住区用地不断增加，居民的生活质量不再局限于房子的档次与质量，他们对户外环境质量的要求逐渐提高。居住小区绿化是建立居住小区众多因素中不可缺少的组成部分。本文在此从设计的角度对居住区园林景观设计做了详细的研究。

选用7种不同的除草处理,探究不同茬次刈割后的单、混用除草技术对紫花苜蓿的安全性、产量及杂草防除效果的影响。结果表明:一茬刈割后施药,杂草鲜重防效最好的是烯草酮+2,4-DB,最差的是2,4-DB;禾草鲜防最好的是烯草酮,其次分别是精稳杀得和精喹禾灵,效果一般;喷施精稳杀得+2,4-DB和精稳杀得+苯达松可显著提高二茬的产量。然而,二茬刈割后施药,杂草鲜重防效最好的却是精稳杀得+苯达松;喷施烯草酮、精稳杀得和精喹禾灵防除禾草的效果非常好,防效在86.18%~100.00%。喷施2,4-DB的单、混用处理三茬产量显著减少。此外,喷施2,4-DB和苯达松的单、混用处理对阔叶草的鲜重防效和株防效都超过66.70%。

With the development of our national economy and the expansion of city, many cities takes the ecological function as the main control of project development in the process of ci-ty development . Based on the development of Yibin, this pap-er discusses the overal planning of Cuiping Mountain humani-stic landscape based on ecological function, hopes our col eag-ues to give guidance.

The yield and quality of alfalfa and weed control effects were investigated by the method of single factor complete randomized block design.Result showed that 2,4-DB and bentazon applied alone or mixture had a better control effect on broadleaf weeds,and control efficiency was 75.80%~90.65%.Haloxyfop-R-Methyl,quizalofop-R-methyl and clethodim had effective control on monocotyledon weeds in alfalfa field,and control efficiency were more than 71.10%.However,2,4-DB decreased the cumulative yield of alfalfa more than 64%.While bentazon+Haloxyfop-R-Methyl,bentazon+Quizalofop-R-methyl and Haloxyfop-R-Methyl improved the yield of alfalfa harvested secondly up to 46.50%,45.28% and 43.06%,receptively.With the comprehensive consideration of herbicide performance,bentazon+Haloxyfop-R-Methyl and bentazon+Quiza lofop-R-methyl showed better results and could be widely applied in alfalfa fields.

Flavourzyme,Protamex,Alcalase,pancreatin,trypsin,AS.1398 neutral protease and papain were employed to hydrolyze the chicken bone paste,and the radical(DPPH·,OH·) scavenging effects and reducibility of the hydrolysates of a protein concentration of 3 mg/mL were studied.It was found that the radical DPPH· scavenging rate of Protamex hydrolyzates was the highest up to 81.44%,and the Flavourzyme hydrolyzates had its highest OH· scavenging rate at 30.32% and reducibility of 0.3(OD value),respectively.Overall,the DPPH· scavenging effect of the hydorlyzates was stronger than the other antioxidant properties.The effects of the protein concentration and degree of hydrolysis(DH) on the ability of DPPH· scavenging were also studied.DPPH· scavenging rate was found to increase with the protein concentration.The radical DPPH· scavenging rate of Flavourzyme hydrolyzates and Protamex hydrolyzates could reach 91.49% and 97.3%,at a protein concentration of 4 mg/mL and 6 mg/mL,respectively.However,there was no positive correlation between the scavenging effects and DH.The hydrolysates would have the strongest antioxidative activity at a specific DH with the highest concentration of the antioxidant peptides.For example,the optimum DH of Flavourzyme,AS.1398 neutral protease,Protamex and pancreatin was 12.59%,23.78%,14.45%,and 20.04%,respectively.

Novel nano-modifier was prepared from calcium-based Montmorillonite. Natural skim was blended with the novel nano-modifier to prepare nano-modified natural skim block. The properties of the natural skim rubber and the nano-modified natural skim block were compared. XRD and SEM results indicated the interlayer space was enlarged with uniform distribution of clay layers. The initial Wallace plasticity (Po) and plasticity retention index (PRI) of the nano-modified skim block were evidently enhanced. The PRI was upto 94.0, the highest when 10% of nao-modified solution was added at a rate of upto 2.0 kg into a 10 g natural skim solution containing 8% dry rubber with a mass ratio of inorganic to organic components being 1:1. The ash content was also increased obviously, and other properties such as tensile stress at a given elongation, tensile strength, and so on were notably improved as well.

Taking the No.342 Provincial Highway (the Section in Wuxi City) for an instance, this article attempts to discuss the method of viresence landscape design of urban road with orientation of green ecology to give a reference to the similar projects.

The Ancient Canal in Wuxi is the miniature and witness of the urban social economy and the historical culture development, which is non-regenerative resource and valuable wealth of the city vouchsafed by ancestor. Protection and development of the Ancient Canal play great roles in the improvement of the environment quality and the landscape image in the city. Taking the landscape design of the Ancient Canal (from Nanjian to Nanmen Hanging Bridge) in Wuxi City as the example, this paper discusses how to protect and develop the landscape design of urban waterfront.

This article analyzes the current research stations of urban colorscape at home and abroad, and presents several control modes of this kind design, based on the case of architectural color planning of Hangzhou Trading Center of Agricultural and Sideline Products.
