摘要
山区小流域由于人类干扰严重,造成水土流失和景观破碎化严重,生态环境脆弱.在对山区小流域景观生态特征分析的基础上,提出了小流域景观建设应依据不同景观功能区的特征,集中于绿色景观建设,大力推行植树造林,增加大斑块和绿色廊道的面积.并以河南省淅川县铁瓦河小流域为例进行分析.
Small watershed in mountainous area is a typical geographical unit with problems such as irrational land use,water loss and soil erosion;landscape fragmentation and fragile ecological environment.Focusing on the green landscape construction,much attention should be paid to protecting aggregated patches,increasing the area of patches and green corridors;greatly planting trees,according to different landscape ecological function area.The Tiewa small watershed,located in the northeast of Xichuan County,Henan Province is taken for a case study.
