采用专家判读、AHP法、指数衰减法、加权法对平煤天安股份五矿矿区土地系统存在的生态环境压力进行了综合评价。结果表明:平煤天安股份五矿矿区土地系统生态环境总压力整体为,轻度环境压力(202hm2,32.90%)>中度环境压力(190hm2,30.94%)>中高度环境压力(154hm2,25.08%)>高强度环境压力(68hm2,11.07%)。其中,资源消耗压力A2最大,其次为环境污染压力A3、生产规模压力A4,自然环境压力A1最小。在评价基础上利用矿区土地的自然环境压力和人为生产压力的分异性,将矿区的土地系统分为保护型、消费型、生产型和调和型4种土地生态功能类型和11种土地生态类型区;平煤天安股份五矿矿区土地利用状况呈现不合理的利用状态,主要体现在具有生态保护功能的保护型土地生态系统的总面积仅为4.94hm2,占地比例为13.1%。
採用專傢判讀、AHP法、指數衰減法、加權法對平煤天安股份五礦礦區土地繫統存在的生態環境壓力進行瞭綜閤評價。結果錶明:平煤天安股份五礦礦區土地繫統生態環境總壓力整體為,輕度環境壓力(202hm2,32.90%)>中度環境壓力(190hm2,30.94%)>中高度環境壓力(154hm2,25.08%)>高彊度環境壓力(68hm2,11.07%)。其中,資源消耗壓力A2最大,其次為環境汙染壓力A3、生產規模壓力A4,自然環境壓力A1最小。在評價基礎上利用礦區土地的自然環境壓力和人為生產壓力的分異性,將礦區的土地繫統分為保護型、消費型、生產型和調和型4種土地生態功能類型和11種土地生態類型區;平煤天安股份五礦礦區土地利用狀況呈現不閤理的利用狀態,主要體現在具有生態保護功能的保護型土地生態繫統的總麵積僅為4.94hm2,佔地比例為13.1%。

The expert interpretation ,AHP method ,exponential attenuation method ,and weighting method are adopted to make a comprehensive evaluation of ecological stress on Pingdingshan Cheonan Company Minmet-als mining area's Land System ;The results show that the overall ecological stress on Pingdingshan Cheonan Company Minmetals mining area's land system is mild environmental stress (202ha ,32 .90% ) > moderate environmental stress (190ha ,30 .94% ) > moderate and high environmental stress (154ha ,25 .08% ) > high environmental stress (68 ha ,11 .07% ) ,in which resource consumption stress A2 is the largest ,then follow the environmental pollution stress A3 ,production scale stress A4 ,and natural environment stressA1 is the smallest .On the basis of evaluation ,utilizing the differentiation of mining area's natural environment stress and human-made production stress ,the land system can be divided into four ecological function type :pro-tection type ,consumption type ,production type ,compromise type ,and eleven land ecological type districts ;Land use in Pingdingshan Cheonan Company Minmetals'mining area is unreasonable ,mainly reflected in that the protection type's land ecological system w hich has ecological protection function only occupies 4 .94ha and its proportion is 13 .1% .
