描述:泰國天空灌溉工程自上個世紀八十年代起每年為泰國東北部季節性乾旱地區提供灌溉用水。In this paper, based on the tracing field infiltration tests into frozen and unfrozen soils with three species of soil texture and eight species of soil structure in seasonal frozen soil regions during three overwinters, the basic infiltration characteristics, reduction infiltration mechanism and major factors influencing soil infiltration characteristics are studied all - sidedly and systematically. to master frozen soil infiltration characteristics and supply scientific directions for winter irrigation
本文基於季節性凍土區田間三種質地、八種結構歷時三個越冬期的凍土、非凍土入滲跟蹤試驗，全面、系統地研究了凍融土壤的入滲特性、阻滲機理和影響凍融土壤入滲特性的主要因素，掌握凍融條件下土壤水分入滲特性，為冬灌及農業節水灌溉提供科學依據。8 ndvi value in oasis is significantly higher than the value in desert, both of them have different rules in monthly variation. irrigation temperature and precipitation have effect on variation of ndvi in oasis, the correlation coefficients of sparse vegetation ndvi in desert with climatic and hydrological factors are insignificant and meaningless in practice. the drive factors of oasis ndvi are only adapted on oasis in arid land and are not fit to desert system in arid land
8 、綠洲ndvi值顯著大於荒漠，二者具有不同的季節變動規律；灌溉、氣溫和降水是綠洲ndvi變化的驅動因子，荒漠稀疏植被ndvi與綠洲氣侯、水文因子相關不顯著或無實際意義；綠洲ndvi的驅動因子只適用於乾旱區的綠洲區域，而不適用於乾旱區荒漠系統。分享友人
