中国是四大文明古国之一,有着悠久的历史文化,其中戏剧文化也占有一席之地,中国戏剧是世界戏剧三大源头之一,中国戏曲文化与希腊戏剧、印度梵剧齐名.戏剧的最早形态是"仪式",在中国最早的表演形式为"傩",傩文化被称为"戏剧活化石",是一种古老文化,也是在中国流传范围最广的仪式文化,在西南地区"傩"分布较广,并衍生出了不少地域特色化的民间小戏,"阳戏"就是其一.文章研究西南地区阳戏的发展脉络,仪式性的活动是人类意识的客观性实践,仪式行为向表演艺术的发展也正是人类意识从娱神到娱人的体现.

Based on the comprehensive study of areal differentiation in natural factors and social-economic factors, land use partition in Xingyi city is adopted to give full play to suitable land use, to mainly reflect the land use structure, layout and development, and to better the production potential of land resource. Combining with the social-economic conditions and the land use status, the paper selects 10 indexes according to the data of Xingyi land change survey, and uses cluster analysis for land use partition in Xingyi. At the same time, the results of cluster quantitative analysis is amended by the latest related planning and industrial layout policy to ensure the objective utility of this partition so as to provide a reference for land use direction, industrial structure layout and other similar areas.

土地资源的可持续利用是一切资源可持续利用的基础,也是经济社会可持续发展的关键,对区域土地资源利用变化及其效益的分析,可深入了解土地资源的利用水平。本文通过对兴义市2005~2011年土地资源利用的变化情况及各地类的经济效益对比分析,以摸清兴义市土地资源利用现状和集约用地水平。并根据当地的实际情况,探讨其存在问题与制约因素,初步提出合理地利用兴义市土地资源的建议,以期为同类地区的土地资源利用提供参考。

不同的构成元素围合的空间形式不同,其演绎出的视觉效果也有所不同。景观的构成元素(地形、建筑、植被、设施等)在各个空间界面(底面、墙面、顶面)中的运用会营造出具有不同感受、功能和形式的空间。

The regression equation,y=-1.846 7+0.337x1+1.970 5x2-0.568x3+0.629 2x4,for calculating the leaf area and relative indexes of Trifolium repens was established by using its leaf length and leaf width as measuring indexes.The results showed that there was a very significant linear correlation between the regression equation and measuring indexes and its correlation coefficient was up to 0.987 3.The mathematical model with the simple and practical advantage can be easily used in measuring leaf area of Trifolium repens.

The general planning, implementation condition and benefits were analyzed in the paper for supplying reference and guide to the new round of general planning on land use in Qingzhen City.

According to the studies on root system of annual ryegrass in the condition of organic fertilizer,the results are as following:Root system of annual ryegrass are mainly distributed in 0~20 cm layer below the surface of soil,which amounted for 86.43%~93.76% in weight,and they are more mainly distributed in 0~10 cm,which amounted for 73.86%～88.06%。The root system growth rate is affected by nature factors and themselves′ factors.Lantiantang,Jiewei and Tegao grew fastest at the third times.Jiewei grew faster than the others at seeding stage,after that time,it grew obviously slower than LanTianTang and Tegao.In all,Tegao grew best at the seeding quantity of 3.00 g/m2.

The variation patterns of relative water content,membrane permeability,praline content and chlorophyll content in white clover leaf blade under high temperature stress were studied.The results indicated that the membrane permeability and praline content were graduall yincreased at 25 ℃ to 35 ℃ for 0.5hours,on the contrast,the relative water content and chlorophyll content decreased gradually,but the variation range was not wide.However,the variation was great while treated under the high temperature more than 45 ℃.Compared with those under the normal temperature 25 ℃,the membrane permeability and praline content increased by 50.62%and 59.89% on average respectively when the temperature increased every 5 ℃.In consequence,the relative Water content and the chlorophyll content decreased by 34.22% and 4.61%respectively.Under the experimental conditions,Whire clover can adapt to 35 ℃,and the critical temperature was ranged from 40~45 ℃,the fatal temperature was 50 ℃.
