基于卫星遥感的齐齐哈尔市气候因子对植被生态质量的影响
Effects of Climatic Factors on Vegetation Ecological Quality in Qiqihar City Based on Satellite Remote Sensing
摘要
Abstract
As an important carrying area of the agricultural core zone of the Songnen Plain and a regional agricultural ecological security barrier,the vegetation ecological status of Qiqihar City has a direct and crucial impact on the safety of grain production and the stability of the ecological barrier function.In order to promote the vegetation ecological protection in Qiqihar City,utilizing MODIS satellite remote sensing data and daily meteorological data,the eco-climatic characteristics of vegetation in this area and the impact of typical drought and flood months on ecological quality since 2000 were analyzed.The results indicated that,from 2000 to 2024,the precipitation during the growing season exhibited an upward trend,while the average temperature showed a slight decline.The net primary productivity(NPP),vegetation coverage,and vegetation ecological quality index during the growing season in this region all displayed an upward trend,with vegetation's carbon sequestration and oxygen release capacity increasing annually.However,the typical drought and flood months had varying impacts on ecological quality.关键词
