摘　　要：为全面提升山核桃林地土壤质量的整体水平,促进山核桃产业可持续健康发展,本研究以浙江临安典型山核桃产区为研究区,以植被覆盖度、坡度、土壤肥力和土壤污染情况作为土壤退化评价指标,采用模糊逻辑综合评价方法结合地理信息系统(geographic informationsystem,GIS)、全球定位系统(global positioningsystem,GPS)、遥感(remote sensing,RS)的“3S”技术,进行林地土壤质量退化程度的空间分析,并提出相应管理意见。结果表明:研究区林地土壤肥力以中度退化为主,仅有1.65%的区域处在高度退化状态,主要集中于龙岗镇北部和清凉峰镇西南部;林地土壤污染整体处于较低水平,仅有6.35%的区域处于中高度以上污染退化水平,主要集中于岛石镇和湍口镇;山核桃林地土壤综合退化程度主要以中低度退化为主,占林地面积的66.50%,高度退化、中高度退化、中度退化和低度退化区域分别占林地面积的0.15%、2.44%、27.45%和3.46%,其中高度退化林地主要分布在清凉峰镇西南部和龙岗镇西部。本研究结果将为山核桃林地土壤质量提升和山核桃产业可持续发展提供理论依据。In order to comprehensively improve the soil quality of Chinese hickory(Carya cathayensis Sarg.)plantation and promote the sustainable and healthy development of hickory industry,a typical C.cathayensis plantation area(Lin’an District,Zhejiang Province)was selected for this study.Fractional vegetation cover,slope,soil fertility and soil pollution condition as evaluation indexes for soil degradation were considered.The spatial analysis of soil degradation degree for Chinese hickory plantation was carried out by fuzzy logic comprehensive evaluation method combined with geographic information system(GIS),global positioning system(GPS),and remote sensing(RS)technologies,and the corresponding management suggestions were put forward.The results showed that the soil fertility of plantation in the study area mainly belonged to the moderate degradation,and only 1.65%of the area was in a high degradation,which was centered in the north of Longgang Town and the southwest of Qingliangfeng Town.The overall soil pollution of the hickory plantation area was at a low level,only 6.35%of which was at a moderate to high degradation,mainly distributed in Daoshi and Tuankou towns.The comprehensive soil degradation of the hickory plantation mainly belonged to moderate and low degradation degrees,accounting for 66.50%of the study area.The high,moderate to high,moderate and low degradation areas accounted for 0.15%,2.44%,27.45%and 3.46%of the study area,respectively.The highly degraded hickory plantation was mainly distributed in the southwest of Qingliangfeng Town and the west of Longgang Town.The results will provide a theoretical basis for improving soil quality and the sustainable development of hickory property.
