Method and problems of composition of ecological and soil maps is observed. It is dealt with scientific approaches to evaluation of ecological functions of soil. The meanings of food chain and factor of self-purification of soils are appraised. Some defects of soiling and using some of background indicators is very relative are examined. Due to the fact that there are some differences of science indicators and they have weak connection with each other it seems complicated to appraise soiling. Ecological assessment frameworks do not exist because of some difficulties of calculations of maximum allowable concentration. It is stressed that assessments of disturbance of soils mainly have economic value. The influence of regional factor takes into account very poor. Data are given about the correlation of soil maps of different ecological focus. It’s given the conditions of migration of compounds in soils. The technological scheme to assess of ecological values of soils with the consideration of problems of each stage of the technological scheme is presented. It’s dealt with possibility to create regional, sectorial and global series of ecological and soil maps.
