Patent number: 11493496Abstract: Methods and systems for estimating a surface runoff based on a pixel scale are disclosed. In some embodiments, the method includes the following steps: (1) calculating a vegetation canopy interception water storage, a litterfall interception water storage, and a soil water storage according to an obtained original remote sensing dataset of a climate element in a study area; (2) calculating a vegetation-soil interception water conservation in the study area based on an established vegetation-soil interception water conservation estimation model according to the vegetation canopy interception water storage, the litterfall interception water storage, the soil water storage, and monthly precipitation; and (3) calculating a surface runoff in the study area based on an established water balance water conservation estimation model according to the monthly precipitation, monthly snowmelt, monthly actual evapotranspiration, and the vegetation-soil interception water conservation in the study area.Type: GrantFiled: April 30, 2020Date of Patent: November 8, 2022Assignee: Institute of Geochemistry, Chinese Academy of SciencesInventors: Xiaoyong Bai, Shijie Wang, Luhua Wu, Fei Chen, Miao Zhou, Yichao Tian, Guangjie Luo, Qin Li, Jinfeng Wang, Yuanhuan Xie, Yujie Yang, Chaojun Li, Yuanhong Deng, Zeyin Hu, Shiqi Tian, Qian Lu, Chen Ran, Min Liu

Patent number: 11300709Abstract: The present invention relates to a method for determining a surface runoff yield in a vegetation-covered area. The present invention improves and integrates a water conservation model with a Zhang's model based on remote sensing data. The present invention constructs a new method for calculating a surface runoff yield in a vegetation-covered area on a spatial pixel scale based on a water balance equation of the vegetation-covered area. This method utilizes real-time dynamic multi-temporal remote sensing data to calculate a vegetation canopy interception water storage, a vegetation litterfall interception water storage, a soil water storage change, a vegetation water conservation, a vegetation evapotranspiration and a vegetation runoff yield. The method realizes the long-term dynamic estimation of the surface runoff yield in regional and global vegetation-covered areas on a spatial pixel scale. It has the advantages of being efficient, fast, accurate, and applicable to large-scale vegetation-covered areas.Type: GrantFiled: April 30, 2020Date of Patent: April 12, 2022Assignee: INSTITUTE OF GEOCHEMISTRY, CHINESE ACADEMY OF SCIENCESInventors: Xiaoyong Bai, Shijie Wang, Luhua Wu, Fei Chen, Miao Zhou, Yichao Tian, Guangjie Luo, Qin Li, Jinfeng Wang, Yuanhuan Xie, Yujie Yang, Chaojun Li, Yuanhong Deng, Zeyin Hu, Shiqi Tian, Qian Lu, Chen Ran, Min Liu
