摘要
以河北省阜平县、武邑县 ,福建省清流县、惠安县作为研究区 ,利用 2 0 0 0年 TM遥感图像 ,通过解译、判读得到景观结构矢量图 ,然后利用景观生态学数量方法分析了研究区农村居民点景观特征的差异及空间分布格局。研究表明 ,研究区农村居民点规模较小 ,平原地区平均面积不到 2 0 hm2 ,山区农村居民点平均面积低于 10 hm2。农村居民点距离较近 ,山区农村居民点平均距离小于 2 .5 km,平原地区农村居民点距离小于 0 .4 hm。农村居民点规模小 ,分布零散 ,适应于农业经济的发展。为了节约居民点用地 ,应采取加快城镇及中心村发展的方针 。
The study area is Fuping,Wuyi county in Hebei province and Qingliu,Huian county in Fujian Province.They are located in plain and mountain areas in northern and southern China respectively.The landscape data are interpreted using Landsat TM images of 2000. The landscape ecology indices are applied to study landscape structure disparity and the density,size,shape,distribution law of rural settlements in study areas.Forest and grassland are the dominant landscape in mountain area while agricultural field and human settlements are the main landscape in plain area.The rural settlements in plain area are bigger in size,even in distribution,nearer in distance;those in mountain area are smaller,uneven and far.The rural settlements are smaller less than 20 hm 2 in plain and 10 hm 2 in mountain areas.The rural settlements are Aerr apart less than 2.5km in mountain area and 0.4 km apart in plain area.The development of the cities and central villages should be encouraged to optimize the rural settlement distribution.
