摘要

The environmental characteristics and degree of pollution of a jagÜey (a small, shallow tropical water-body) in Mexico were identified by means of an environmental impact matrix. JagÜeys are important as their main sources of water are the subsurface water-table and rainfall, however, they have not been studied because of their small size. A flow diagram was designed to incorporate the main climatic, geological and hydrological environmental factors, as well as physico-chemical data on sediment and water qualities, and biological, technostructural and socioeconomic aspects. The resulting index of –90 in the environmental impact matrix indicates a severe negative impact on jagÜeys from the input of allochtonous nutrients because of their small depth, limited circulation and the high rate of evaporation. The jagÜeys studied appear in a state of hypertrophy and senility, despite geological youth.
