BACKGROUND
The present study was conducted to explore the diversity pattern of spring vegetation under the influence of topographic and edaphic variables in sub-tropical zone, District Malakand. In the present vegetation study, 252 species of 80 families were recorded in the study area. It included 39 species of trees, 43 species of shrubs, 167 species of herbs and 3 climber species. As a whole, 12 communities were established on the basis of topographic and edaphic characteristics in 12 different stations.
RESULTS
The results of the present study revealed that all diversity indices (species diversity, evenness index, species richness index, maturity index) during spring showed that the communities in plains lying at lower altitudes had higher diversity while the communities formed at high altitudes had lower diversity. The results of the similarity index showed that there was low similarity (below 50%) amongst the communities in different stations.
CONCLUSIONS
It can be concluded that variations in topographic and edaphic factors affect species diversity and communities pattern.
背景
本研究旨在探讨亚热带马拉坎德地区地形和土壤变量影响下的春季植被多样性模式。在本次植被研究中，研究区域记录了80科的252种植物。其中包括39种乔木、43种灌木、167种草本植物和3种攀缘植物。总体而言，根据12个不同站点的地形和土壤特征建立了12个群落。
结果
本研究结果表明，春季所有多样性指数（物种多样性、均匀度指数、物种丰富度指数、成熟度指数）显示，低海拔平原地区的群落多样性较高，而高海拔地区形成的群落多样性较低。相似性指数结果表明，不同站点的群落之间相似性较低（低于50%）。
结论
可以得出结论，地形和土壤因素的变化影响物种多样性和群落模式。
