A s t he main c ontent o f a r esearch p reject funded b y t he national natural science foundation of china ( nsfc ) , the dissertation studied many aspects on construction industry , and delivered the following results : 1 . the dissertation firstly makes a theoretical analysis on the general rule of construction growth , followed by an empirical test on the data of 34 countries in different development stages . this cross - sectional analysis and regression model investigate the relationship between the share of construction value - added ( cva ) in gross domestic product ( gdp ) and gdp per capita 在对建筑业的成长一般规律进行理论分析的基础上，利用34个处于不同发展时期国家的横断面数据，回归模拟出建筑业增加值在gdp中所占比重与人均gdp的关系，结果发现：建筑业增加值在gdp中的比重随人均gdp增长而呈现三次曲线关系，先上升，后下降，然后随人均gdp增长还有可能继续上升；第一次达到的正常情况顶点位置的产值比重(产业增加值gdp )为7 . 28 ，中国建筑业正处在向这一顶点攀升的过程中。
Previous researchers have always determined the sp atial distribution patterns ( sdp ) of castanopsis kawakamii with a sample - dis tance method . however , the distribution patterns may be affected by the quadrat si ze and , in the course of analysis , the density differences among the cluster plots are not considered ; therefore , differences of cluster plot size and the dispersi on degree among individuals of cluster plots can not be known . authers of this pa per have determined the spatial distribution patterns of castanopsis kawakamii population in different habitats by means of non - quadrat distance method and a nalysed the pattern intensity and grain of the sdp . the pattern intensity is defi ned with the relative density differences and the pattern grain can embody the d ispersion degree of the individuals in the plots , and the dispersion degree among the plots . the determined results are as follows . the intensities of the species range in order from strong to week : litsea mollifolia p . kawakamii i . purpure a r . cochinchinensis c . kawakamii c . carlessii d . oldphamii s . superba . the gra ins of the species queue in order from coarse to close : s . superba = litsea mollif olia r . cohinchinensis c . kawakamii = i . purpurea c . carlessii p . racemosam d . oldp hamii . these determined results tally basiclly with the results authers of this paper have got in determining the same plots by means of aggregate index access ing method . in view of this , it is held that the sdp of c . kawakamii is closely related to the habitats and biological features 前人都是采用样方方法对格氏栲种群数量的空间格局进行测定，而格局分布有可能受样方大小的影响，且分析过程中没有涉及聚块间密度差的问题，因而无法掌握种群的聚块大小差别及聚块内个体间的离散程度.本研究采用无样方距离法，测定不同生境的格氏栲种群空间格局，分析格氏栲种群格局的强度和纹理.强度以聚块和间隙的密度差来定义，纹理则是体现聚块内个体间的离散程度与诸聚块间的分离程度.测定结果表明，格氏栲种群格局强度从高到低排列次序为：木姜子蚊母树冬青茜草树格氏栲米槠虎皮楠木荷；格局纹理从粗到细的顺序是：木荷=木姜子茜草树格氏栲=冬青米槠蚊母树虎皮楠.这一测定结果与作者采用聚集度指标测定相同样地格氏栲种群空间格局的结果基本相符.因此，格氏栲空间格局类型及分布与格氏栲生物学特性及生境的关系密切
