Abstract: Ecological researches on the intercropping of forages with wheat were carried out during 1989-1990.Theitems include relative light intensity,temperature,temperatural variation,relative humidity and soil rnois-ture and nutrient contents. The results are summarized in detail and effective measures for soil protection are mentioned.

Key words: land surface temperature, relative heat island intensity, topographic gradient, population gradient, GDP gradient, central area of Chongqing City.
