【摘要】：為了定量評估金屬礦山生態(tài)安全現(xiàn)狀,建立了金屬礦山生態(tài)安全效應(yīng)評估指標(biāo)體系及評估等級標(biāo)準(zhǔn),采用模糊層次法(FAHP)確定生態(tài)安全效應(yīng)各子系統(tǒng)及其指標(biāo)的權(quán)重,并引入可變模糊集理論,建立基于FAHP與可變模糊集的礦山生態(tài)安全效應(yīng)評估耦合模型.利用該模型對安徽某大型銅礦的生態(tài)安全效應(yīng)進(jìn)行評估,經(jīng)計(jì)算該礦在生產(chǎn)效應(yīng)、自然稟賦效應(yīng)和社會經(jīng)濟(jì)效應(yīng)子系統(tǒng)上屬于Ⅱ級,在環(huán)境效應(yīng)子系統(tǒng)上屬于Ⅲ級,礦山綜合生態(tài)安全效應(yīng)狀態(tài)屬于Ⅱ級.結(jié)果表明:該模型計(jì)算簡便、可信度高,與其他評估方法得到的結(jié)果相一致,亦符合礦山實(shí)際情況.
[Abstract]:In order to quantitatively evaluate the present situation of ecological safety in metal mines, the evaluation index system and evaluation grade standard of ecological safety effect of metal mines were established. The weight of each subsystem and index of ecological safety effect was determined by using fuzzy hierarchy method (FAHP). The coupling model of mine ecological safety effect evaluation based on FAHP and variable fuzzy set is established by introducing variable fuzzy set theory. The ecological safety effect of a large copper mine in Anhui Province is evaluated by using this model. It is calculated that the ore belongs to class 鈪，
