A STUDY ON ECONOMY EVALUATION ON THE PROFIT AND LOSS OF GEOLOGIC ENVIRONMENTAL QUALITY ABOUT GEOLOGIC ENVIRONMENTAL EXPLOITATION PROJECT

The problems of environmental geology refer to the geologic phenomena, incidents or accidents arising from action of environmental geology. The action is mainly the mutual influence between human activity and geologic environment. When human activity is uncoordinated with objective laws of the geologic environment, the problems of environmental geology or economic loss would occur.Therefore,the level and the changing orientation of geologic environmental quality are relative to the types of human activity,particularly relative to human intentional-activities of geologic environmental exploitation project. The geologic environment fitting to mining may not fit to urban construction,and fitting to water conservancy and hydroelectric projects may not fit to communication,and so on.Economy evaluation on the profit and loss of geologic environmental quality is exactly to depict the level of the profit and loss of geologic environmental quality about geologic environmental exploitation projects and the

发展接续产业避免资源型城市“林竭城衰”——以黑龙江伊春市接续产业发展研究为例

伊春市是以森林资源为主的资源型城市,是全国最大的林区之一,经过50年的超负荷开发,已面临“林竭城衰”的困境。保护好森林,发展区域经济,实现林都的可持续发展,必须发展好接续产业。国家已把伊春市作为资源型城市经济转型的试点。文章在分析伊春市经济转型的结构性障碍、特有主导资源———森林资源开发利用损益评价、接续产业发展优势基础上,提出了伊春市新时期生态经济社会持续发展的线路图。

工程地质环境质量损益经济评价研究

本文阐述了地质资源开发工程地质环境质量损益经济评价的基本含义与地质资源开发利用中的主要环境地质问题或负效应。建立了地质资源开发工程地质环境质量损益经济评价的指标体系和评价模型。并以某地区规划采矿工程地质环境质量损益度评价为例，对地质资源开发工程地质环境质量损益经济评价作了简要说明。
