Article Synopsis
- * Results indicated that water in forest areas showed smaller average values and variation in δO isotopes compared to terrace areas, suggesting different influences of these landscapes.
- * The elevation impact on hydrogen and oxygen isotopes was notable, but it was influenced more by the landscape gradient rather than precipitation patterns, leading to enhanced δO differences between forest and terrace patches.
Analysis of hydrogen and oxygen stable isotopes is an effective method to track the water cycle in watershed. Impact of landscape pattern on the isotope effects of spring water is a new interdisciplinary topic between landscape ecology and isotope hydrology. Taking the Quanfuzhuang River basin located in the core area of UNESCO World Cultural Heritage of Honghe Hani Rice Terrace as the object, collecting the monthly samples of 78 points of spring water and 39 precipitation at altitude of 1500 m (terraces), 1700 m (terraces) and 1900 m (forest) from March 2015 to March 2016, we analyzed the hydrogen and oxygen stable isotopes of water samples under the different landscape types.
