摘要/Abstract

摘要： 选择河北省遵化市(39°55'～40°22'N,117°34'～118°14'E),调查了城郊和乡村在东南西北4个方向上以及市区的植物多样性,同时考察了不同取样点土壤养分的差异结果表明,西部和北部接近,而东部和南部的土壤养分特殊,城郊与乡村明显差异;西部物种丰富度低于其它方向,而南部最高,这种差异由草本造成;城市与东南西北4个方向的生物多样性差异明显;城市植物多样性与城郊和乡村呈现梯度变化;本研究统计的物种总数只有126种,而与之同纬度的北京东灵山区却有高等植物997种.城市化的影响是引进了一些观赏物种,区域地形和土壤养分等自然特征的影响微弱.

Abstract: Species diversities of urban,suburb and rural areas,as well as north,east,south and west were separately investigated in Zunhua City (39°55'～40°22'N,117°34'～118°14'E),Hebei Province,China.Soil samples were collected to show the difference of soil nutrients among those sites.The results showed that the soil nutrients of south and east were special,and those of west and north were similar.It was very different between suburb and rural.The plant diversity of west was lower than all the other directions,whereas south had the highest one.Herb was the reason of the difference.The urban area was very different in biodiversity compared with north,east,south and west.The plant diversities of urban,suburb and rural areas were of gradient and in accordant with the intensity gradient of land use.The total species in this area was 129,whereas the total species in Donglingshan,which is at the same latitude,was 997.The impact of urbanization was the introduction of some horticultural species,and the influence of topography and soil nutrient was very weak under this circumstance.

Key words: Land use, Urbanization, Biodiversity
