摘　　要：珠巴洛河流域内生物多样性较高,生态区位重要。采用GIS技术,基于耕地、园地及建设用地3类干扰类型研究该流域2003—2019年人为干扰程度。结果表明,在研究期内,该区域的耕地面积明显减少,园地面积明显增加,特别是2011—2019年间增减幅度较大,耕地主要转化为园地;建设用地面积呈逐渐增加趋势;整体上流域受人为干扰程度在逐渐增加,但受干扰区域相对集中,主要位于珠巴洛河中下游及其较大支流沿岸;流域范围内自然保护区的各功能区均受到不同程度干扰,其中实验区所受干扰程度明显高于整个流域。The Zhubaluo River basin has high biodiversity and important ecological location.The degree of human disturbance in the basin from 2003 to 2019 was studied by using GIS technology based on three interference types of cultivated land,garden land and construction land.The results showed that the area of cultivated land in this region decreased significantly,and the area of garden land increased significantly during the study period,especially from 2011 to 2019,and the cultivated land was mainly transformed into garden land;the area of construction land showed a gradual increase trend;on the whole,the degree of interference in the basin increased gradually,but the interference areas were relatively concentrated,which mainly located in the middle and lower reaches of the Zhubaluo River and along the banks of the larger secondary tributaries;all the functional areas of the reserve within the basin were disturbed to varying degrees,and the interference degree of the experimental area was significantly higher than that of the whole basin.
