2.low-middle
4.Three geothermal types exist in whole Yunnan region: high geotemperature type with the Moho temperature >960℃ and the crustal geothermal gradient >2℃/100m, low geotemperature one with the Moho temperature <700℃ and the crustal geothermal gradient <1.5℃/100m, and middle geotmeperature one with the Moho temperature lying between the former two types and the crustal geothermal gradient 1.5 ~ 2.0℃/100m.
5.and those for the middle high turbidity water are R 2=0.877 and MRE= 0.564 . MRE for retrieving chlorophyll concentration in the middle high trubidity water is large, especially in the low chlorophyll concentration area ( C chl <1mg/m 3), which indicates that the model for retrieving low clorophyll concentration in the middle high trubidity water remains to be further improved.
