Abstract: (1460 Views)
Identifying the influencing variables on the survival of aquatic plants is one of the most important management issues in Relationship with conservation planning. Among the environmental variables, temperature plays an important role, but collecting temperature information is expensive. Earth surface temperature is one of the widely used thermal remote sensing products that can be useful in this field. In this study, by calculating the average seasonal temperature of the surface of the earth, the fluctuation of temperature in the presence of water hyacinth (Eichhornia crassipes) in Chamkhale city of Guilan province was investigated. Earth's surface temperature was calculated using the Planck function method in the Google Earth Engine system. Then, all the samples taken from the study area were sorted based on decreasing latitude, and the trend of seasonal changes in temperature was checked for each one using the modified Mann-Kendall test. Placement of presence points in hot and cold thermal islands was also done for each season at a significance level of 99% using the Getis-Ord Gi test. The results indicated that there are the highest and lowest temperatures in the areas where water hyacinth is present in summer and winter. In all seasons of the year, with decreasing latitude, the surface temperature increased in the regions where the species is present. No cold thermal islands were formed in the presence areas of the species, but in summer, warm thermal islands covered the presence areas.
