融合多源数据的广西典型灌区作物种植结构、蒸散发及土壤墒情反演研究
Research on crop planting structure,inversion of evapotranspiration and soil moisture in typical irrigation zones of Guangxi by integrating multi-source data
摘要
Abstract
Guangxi is the crucial agricultural production base in South China.Its crop planting structure and water resource utilization efficiency play vital roles in regional agricultural development.Taking the Changqi Irrigation Zone in Guangxi as the research object,based on the Sentinel-2 multi-temporal remote sensing data,the Penman-Monteith model and the Surface Water Content Index(SWCI),a systematic analysis was made on the characteristics of crop planting structure,evapotranspiration dynamics,and soil moisture distribution pattern in the irrigation zone.The results demonstrated that:①The proportion of crops planted in this irrigation zone is 8.45%for rice,0.18%for corn,and 10.13%for sugarcane;②Evapotranspiration exhibited a spatial pattern characterized by higher values in the northwestern regions and lower values in the southeastern areas;③Soil moisture content displayed a distribu-tion trend of higher in western regions compared to eastern areas.关键词
