摘要对腾格里沙漠东南缘2种人工植被柠条和油篙在4种配置方式下地上部分的生长动态进行了研究，结果表明：不同配置方式下它们的密度、高度、冠幅和生物量基本不变或略微呈下降趋势；油篙新梢的年生长动态呈s型曲线，柠条新梢春季生长速度较快， 7月份以后生长速度缓慢或基本停止生长；柠条、油篙地上生物量和叶面积指数的年变化均表现为双峰型， 4种配置方式下共有8种1年生植物人侵，并具有较高的植被盖度；同其它3个样地相比，纯油篙样地1年生植物的密度、盖度和生物量明显偏低。
- 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
