【Abstract】 Objective To investigate lake water therapy resources,and to analyze its correlation with health resort.
Methods Using Landsat 8 OLI_TIRS and MODIS 3 km AOD remote sensing images from the Geospatial Data
Cloud,and data processing platforms of ENVI and ArcGIS software,natural therapeutic resources of lake water health
resorts in nine different regions in China were evaluated.Changing patterns and differences in natural resources across
regions were qualitatively analyzed for their therapeutic value. Results The nine lake water bodies in different
regions were rich in natural resources and had diverse landforms.There were significant differences in precipitation,
temperature,sunshine,humidity,frost-free period,and vegetation cover(P<0.05).In the past 10 years,the average annual
precipitation has exceeded 400 mm,and Hangzhou West Lake and Jiangxi Poyang Lake have even exceeded 1 400 mm.
Except for Yunnan Dianchi Lake,the other lakes were all below 400 m of sea level.The average annual temperature of
Jilin Songhua Lake and Heilongjiang Jingpo Lake was below 4 ℃,and the average annual minimum temperature of
Jilin Songhua Lake,Heilongjiang Jingpo Lake,Suzhou Taihu Lake,Shanxi Yuncheng Salt Lake,and Wuhan East Lake
was below 5 ℃.The average annual minimum temperature of the other lakes fluctuated between 8-16 ℃.Except for
Yunnan Dianchi Lake,the average annual maximum temperature was below 15 ℃,and the average annual temperature
of the other lakes fluctuated between 15-30 ℃.Tianjin Cuiping Lake had the longest average annual sunshine duration
of 2 500 h,while Suzhou Taihu Lake had the shortest average annual sunshine duration of 1 630.4 h.Shanxi Yuncheng
Salt Lake had the longest average annual sunshine duration of 3 200 h. The average vegetation coverage of
Heilongjiang Jingpo Lake and Jiangxi Poyang Lake was 90%,while the average vegetation coverage of Suzhou Taihu
Lake, Shanxi Yuncheng Salt Lake, and Wuhan East Lake was below 50%. The distribution of natural resources at
different lake resorts showed certain north-south differences and seasonal fluctuations.Conclusion Lake water resorts
possess abundant natural resources that can meet the needs of a wide range of populations.Comprehensive evaluation
and analysis of the therapeutic value of each lake water resort should be conducted.It is important to fully exploit its
natural advantages and develop personalized recuperation plans for different populations,so that natural resources can
play a greater role in recuperation and chronic disease rehabilitation.
