阜新矿区矸石山植被技术影响因素

Influential factors of mining waste dump vegetation technology in Fuxin mining area

调查了阜新矿区高德东山、海州排土场不同年代的矸石山风化壳表层植被情况,研究分析了植物生长的表层土壤结构和营养成份,得出影响植被生长的主要因素是土壤结构及其厚度、养分含量。提出了阜新地区矸石山表层植被技术的关键是风化壳表层改良和氮的固定,可充分利用阜新地区的非金属矿产资源和粉煤灰。

The surface layer vegetation of weathering crust of mining waste dump, which is located in the Gaode-dongshan and Haizhou dumping site in Fuxin mining area, was investigated. The topsoil structure and nutrient content of the plant growth were studied and analyzed. Results show the main factors that influenced the vegetation growth were soil structure, thickness and nutrient content. The essence of the technology of surface layer vegetation of mining waste dump in Fuxin mining area, i.e. the modification for surface weathering crust and fixation for nitrogen, is presented. The nonmetal mineral and fly ash in Fuxin area can be fully used.
