生态脆弱区植被覆盖度变化及驱动力分析——以鄂尔多斯市为例
Analysis of fractional vegetation cover changes and driving forces in ecologically fragile areas:taking Ordos City as an example
摘要
Abstract
Taking Ordos City as an example,the variation law of regional vegetation coverage from 2000 to 2018 was studied.Natural and human activity factors were selected,and the influence of different driving factors on the change of vegetation coverage in Ordos City was analyzed by geographical detector.The results showed that:(1)The overall distribution of vegetation cover in Ordos City showed the characteristics of high in the south and low in the north,high in the east and low in the west.The decrease in low vegetation cover from 2000 to 2010 was the largest,1.81×104 km2,and the decrease in no vegetation cover was the smallest,1.91×103 km2.The decrease in medium vegetation cover from 2010 to 2018 was the largest,1.44×104 km2,and the high vegetation cover reduction area was the smallest at 1.45×103 km2.From 2000-2018,the vegetation cover of Ordos City had generally become better,and the mean value had a fluctuating upward trend.(2)The quantitative analysis of the explanatory power of vegetation cover in Ordos City found that the strongest explanatory power was found for annual precipitation among climate-type factors(q=0.229)and for grain yield among human activity-influenced factors(q=0.207).The explanatory power of factor interaction on the spatial distribution of vegetation cover was greater than that of individual factors,and the combined effect of natural and anthropogenic factors was the root cause of vegetation cover variation in Ordos City.(3)Since 2000,due to the uneven economic and population development of Ordos city,the mining area has led to the destruction of vegetation and the reduction of vegetation cover in some areas,and with the implementation of a series of ecological management initiatives,the regional vegetation cover has been restored.Therefore,the implementation of policy measures is also an important reason for the higher vegetation cover in the region.It is more conducive to the restoration of vegetation in ecologically fragile areas by alleviating the contradiction between people and land and controlling the coordinated development of population and regional economy.关键词
