摘要
为了探究平顶山市生境质量的时空演变和退化情况,基于1990—2020年4期土地利用/覆盖(LULC)数据,结合InVEST模型和Google Earth Engine(GEE)云计算平台,对平顶山市土地利用类型、植被覆盖度和生境质量的时空变化特征进行了定量分析,并探讨了生境质量的驱动因素。结果表明,平顶山市的城镇及建设用地面积在这30年间从131.56 km^(2)增至387.43 km^(2),而草地面积减少约276.71 km^(2),部分转化为林地。2000年至2004年间,植被覆盖度(归一化植被指数(NDVI))降低,2015年后又明显上升,显示出生态改善趋势。生境质量总体呈下降趋势,生境质量等级较低的区域有所增加;但优等生境质量的区域面积也有所增加,集中分布在鲁山县、舞钢市南部和宝丰县西部。生境退化区域集中在白龟湖水库周边,主要受城镇扩张的影响。建议未来加强引导,合理规划土地利用,以促进平顶山市的绿色和可持续发展。
In order to investigate the spatial and temporal evolution and degradation of habitat quality in Pingdingshan City,this study quantitatively analyzed the spatial and temporal characteristics of land use,vegetation cover and habitat quality in Pingdingshan City based on the 4-period land use/cover(LULC)data for 1990-2020,combined with the InVEST model and the cloud computing platform of Google Earth Engine(GEE).And the driving factors of habitat quality were explored.The results showed that the area of urban construction land in Pingdingshan City increased from 131.56 km^(2) to 387.43 km^(2) in 30 years,while the area of grassland decreased by about 276.71 km^(2),partly converted to forest land.Vegetation cover(normalized difference vegetation index(NDVI))decreased between 2000 and 2004,and then significantly increased after 2015,showing a trend of ecological improvement.Habitat quality generally showed a decreasing trend,with the area of low-quality habitat areas increasing;the area of excellent habitat areas also increased,concentrating in Lushan County,the southern part of Wugang City and the western part of Baofeng County.Habitat degradation areas concentrated around White Turtle Lake Reservoir,mainly affected by the expansion of cities and towns.It was suggested that guidance be strengthened and land use be rationally planned in the future to promote green and sustainable development in Pingdingshan City.
