- 摘要:
- 利用MODIS-NDVI数据研究了2000—2012年山西省生长季平均NDVI的时空变化特征，并分析了气候变化和人类活动对生长季平均NDVI变化的影响。结果表明：（1）13 a来山西省山地落叶阔叶林生态区、农业与草原生态区、汾河谷地农业生态区生长季平均NDVI均呈显著增加趋势，增长率分别为0.052/10 a，0.079/10 a，0.049/10 a。（2）山西省植被变化存在明显的空间差异，改善区占全省面积的73.76%，主要分布在太行山、太岳山、吕梁山、中条山等地区；而退化区占全省面积的3.29%，主要分布在太原盆地及临汾盆地的边缘地区。（3）NDVI变化是气候变化和人类活动共同影响的结果。不同生态区NDVI对气候变化的响应不同。其中，前一年11月至5月降水增多可能是山地落叶阔叶林生态区NDVI增加的主要原因，前一年12月至1月气温降低和2—5月降水增多可能是农业与草原生态区NDVI增加的主要原因，5—9月气温降低和前一年11月至8月降水增多可能是汾河谷地农业生态区NDVI增加的主要原因。而人类活动对NDVI变化的影响主要表现在退耕还林、防护林建设、采矿、城市扩张等方面。
- Abstract:
- Spatiotemporal variation of growing-season average NDVI in Shanxi Province was analyzed based on MODIS-NDVI during the period from 2000 to 2012, and the influence of climate change and human activities impacting on vegetation growth were discussed. The result showed that: (1) the growing-season average NDVI of three ecological districts in Shanxi Province which were the Mountain Deciduous Broad-leaved Forest Ecological District, the Agriculture and Grassland Ecological District and the Fen River Valley Agricultural Ecological District showed a significant increase trend; the growth rates of three ecological districts were 0.052/decade, 0.079/decade and 0.049/decade, respcectively; (2) there were obvious spatial differences about vegetation change in Shanxi Province, the greening area accounted for 73.76% of the total area that was mainly distributed in Taihang Mountain, Taiyue Mountain, Lüliang Mountain, Zhongtiao Mountain, the degraded area accounted for 3.29% of the total area that was mainly distributed in the edge of Taiyuan Basin and Linfen Basin; (3) both climate change and human activities were important factors on vegetation variation. Different districts had different responses to climate change. Increasing precipitation from November to May probably was the main reason for average NDVI increase in the Mountain Deciduous Broad-leaved Forest District. Decreasing temperature from December to January and increasing precipitation from February to May probably were the main reasons for average NDVI increase in the Agriculture and Grassland District. Decreasing temperature from May to September and increasing precipitation from November to August probably were the main reasons for average NDVI increase in the Fen River Valley Agricultural District. In addition, the impacts of human activities on the NDVI changes mainly were observed in forestland shifted from the cropland, shelter forest construction, mining, urban expansion.
