河北太行山区河谷土地利用特征研究

Characteristics of land-use in river valleys of Taihang mountains area,Hebei Province

  • 摘要: 以景观生态学原理研究分析太行山区7条河流主流河谷土地利用特征结果表明,各河流属性、地貌特征、水流特性等存在一定差异,但河谷内土地利用总体格局一致,土地利用类型中农田为绝对优势,占50%~80%,村庄次之,占20%左右,林地<10%,土地利用类型总体表现为由上游向下游增多的趋势。河谷内土地斑块较破碎,平均每1000m 长河谷内分布5~6个土地斑块,阜平县河道占河谷面积比例基本在15%~30%问变动,元氏县保留河道比例为10%以下。

     

    Abstract: Using the theory of landscape ecology,the land-use characteristics of main valleys are analyzed in 7 rivers of Taihang mountains area of Hebei Province.The results show that the valley land-use patterns of 7 rivers are similar despite that the river properties ,landforn'l characteristics and water situations are different from each other,and farmland occupies 50% ~ 80%.village 20% and forest land less than 10% of valley area.The land-use types increase from upstream to downstream.The land patches are relatively fragmented,and the number of land patch is 5 or 6 per 1000 meters valley.The reserved watercourse oceupies 15%~ 30% of valley area in Fuping County.and no more than 10%in Yuanshi County.
