Ecological Functions as a Fundamental Integral Characteristics of Peculiarities of Abiotic Environments of Ecosystem - Lithosphere, Pedosphere, Atmosphere and Hydrosphere

The achievements of present regulatory and technical base for assessing quantitative indicators of ecosystems state are shown relying on the statistics of types of jobs for studying the abiotic spheres of the Earth (lithosphere, pedosphere, atmosphere and surface hydrosphere) as a part of engineering-ecological survey. Those achievements regarding to the regulation of indicators of state of abiotic spheres of ecosystem are described. Ways for further improvement of regulatory and technical base have been outlined using the doctrine of ecological functions of the lithosphere as a fundamental integral characteristic of abiotic spheres of ecosystems and the systematization of individual indicators by introducing of four categories of integral indicators (resource, geochemical, geophysical and geodynamic). Attention is drawn to the need to elaborate the integral indicators of all abiotic spheres of ecosystems basing on development of ecological geology. Various approaches for assessing of such integral indicators are considered. Variant of their determination on the base of summary indicators method is proposed.
