摘      要：The changes in species composition, abundance and forest stand structure were analyzed across altitudinal regimes in tropical forests of Eastern Ghats of northern Andhra Pradesh, India. Three 1-ha plots were established with one each in low, medium and high altitudes. A total of 153 species, 2129 stems （709 stems .ha^-1） of ≥10 cm girth were enumerated. Species richness and diversity pattern varied along altitudinal gradient and increased with the altitude. Species richness varied from 52 to 110 species-ha^-1 and stand density from 639 to 836 ***^-1 with average basal area of 34.39 m^***^-1. Shannon-Wiener index （H＇） ranged from 4.55 to 5.17. Low altitude （i.e., Site 1） is dominated byXylia xylocarpa （59.22） and Lagerstroemia parviflora （23.90）, medium altitude （i.e., Site 2） by Xylia xylocarpa （45;50） Bursera serrata （17.29）, and high altitude （i.e., Site 3） has Schleichera oleosa （28.25） Pterocarpus marsupium （26.55） as predominant species. Taxonomically, Rubiaceae （12 species）, Fabaceae （12）, Euphorbiaceae （11）, Rutaceae （7） and Lanraceae （7） were dominant families. Density-wise, Fabaceae, Combretaceae, Euphorbiaceae, Anacardiaceae and Myrtaceae were abundant. Thus, conservation assessment based on altitudinal regimes and the information on species structure and function can provide baseline information for monitoring and sustaining the biodiversity.
