Fellow of the "Best Scientists of Russia" from 2003 to 2004.

The main areas of scientific activity are environmental protection, mining ecology, geochemistry of mining technogenesis, forest ecology, monitoring of environmental changes;

Lyudmila Timofeevna Krupskaya is a well–known expert in the field of studying the problem of rational use of natural resources in the process of subsurface development, including the reclamation of lands disturbed by mining operations. She gave a theoretical justification and created a methodology for practical measures to reduce the negative impact of mining on ecosystems, to restore land productivity in man-made landscapes. Krupskoy L.T. created the scientific foundations of a strategy for the sustainable development of natural systems in mining areas. The necessity of a genetic approach to the research of the problem of anthropogenic pollution of the components of the biosphere in the process of mining technogenesis is substantiated. Test systems (cytological and cytogenetic) have been developed, which made it possible to assess the state of environmental objects in the mining area, on the basis of which bioindication of the environmental stress of the mining area was performed and a classification grouping of mining enterprises was developed, taking into account their negative impact on the natural environment. Krupskoy L.T. For the first time, patterns of ecosystem transformation have been identified for mining enterprises in the south of the Far East and patterns of changes in the ecological properties of biota from the level of environmental hazard of mining processes have been graphically depicted, and the dependence of pollen sterility on the radius of influence of anthropogenic pollution associated with the development of mineral raw materials has been determined. It is shown that the visually distinguishable reaction of plants has a threshold character. In areas with a higher level of anthropogenic pollution, pollen sterility in bioindicator plants is significantly increased compared to the control. For the first time, a system of environmental criteria has been proposed and tested to diagnose the state of the habitat of living organisms in the mining process. Biogenic principles for assessing environmentally sound mining technologies have been developed for the first time. A method for assessing the negative impact of mining waste on ecosystems is proposed, and the integral level of genetic and environmental hazards of their impact is determined. Based on the developed principles, a classification of the degree of man-made disturbance of natural systems during subsurface development has been created. For the first time, a method for safely storing the "tailings" of enrichment during ore gold mining has been developed for monsoon climate conditions. The novelty is confirmed by the Patent of the Russian Federation. Krupskoy L.T. has developed proposals to improve the environmental safety of soils and biota in the mining zone and a conceptual model for microbiological monitoring of pollution of environmental objects. For the first time, criteria for the selection of aquatic plants for biotechnological wastewater treatment of a gold extraction plant have been identified (using the example of CJSC Mnogovershinnoye) and the possibility of using Lemna minor has been experimentally proven. Krupskoy L.T. proposed a new effective method of recultivation of lands disturbed by mining operations, as well as other ways to protect soils (from degradation) and biota, protected by Copyright and Patents of the Russian Federation. She implemented these methods at mining enterprises in the Khabarovsk and Primorsky Territories, as well as in the Sakhalin and Amur regions, covering an area of more than 400 hectares. Krupskaya L.T. provides a scientific justification for the priority areas of mining waste disposal in the Khabarovsk Territory and the general model of tailings pond reclamation. The development of principles for forecasting the environmental risk of transformation of ecosystems in the Amur region in the process of developing solid minerals continues. Krupskaya was the scientific director of the basic research grants: "Integration" (State support for the integration of higher education and fundamental science), "Program of the Ministry of Education of the Russian Federation", "Financial support for scientific programs of the Far Eastern Branch of the Russian Academy of Sciences", responsible executor of the sections "Complex expeditionary studies of the natural environment in the Amur River Basin" and the Federal Target Program of the Russian Federation, etc.;
