摘要
沂蒙山区植被格局变化受多方面影响,在驱动力分析的基础上,构建驱动力评价指标体系。综合运用空间主成份分析和GIS的先进技术,对沂蒙山区植被格局变化的自然质量、人为干扰和驱动力进行评价。研究表明,沂蒙山区植被格局变化的驱动力水平以显著和较显著为主,二者面积之和占研究区总面积的66.57%。自然条件差、人类社会经济活动的干扰是植被格局趋于退化的重要原因。
Many factors affect the changes of vegetation pattern in Yimeng mountain area.Based on the analysis of factors,this study sets up an index system of driving force.Using both spatial principal component analysis and GIS＇ advanced technology,this study gives an assessment of Yimeng mountain area nature quality,human disturbance and driving force.The results show that the level of driving force is mainly about remarkable and obviously remarkable which accounted for 66.57% of the total land area.Poor natural conditions and disturbance of human economic and social activities are the important cause to vegetation pattern＇s degradation.
