摘　　要：极限条件法是目前土地复垦适宜性评价中应用最广泛的一种方法。文章应用极限条件法,对广安桂兴石灰岩矿损毁土地进行土地复垦适宜性评价。评价中采用地形坡度、表土层厚度、周围土地利用现状、排水条件、地表浅层物质组成和生产管理便利性等6个主要因子进行判定,并结合自然条件、社会经济、政策因素和公众意愿等因素,最终确定拟复垦土地的复垦方向。结果表明:评价总面积为76.982 8hm^2,适宜复垦为有林地的面积为39.371 2hm^2,适宜复垦为耕地的面积为34.747 1hm^2,适宜自然留置、自然积水形成坑塘水面的面积为2.864 5hm^2。通过研究,建立了该区矿山土地复垦适宜性评价指标体系。The limit condition method is the most widely used method in land reclamation suitability evaluation. This paper applies this method to evaluate the suitability of land reclamation for damaged land of Guixing limestone mine in Guang’an, Sichuan. Six major factors such as topographic gradient, surface soil thickness, surrounding land status, drainage conditions, surface shallow material composition and production management convenience in combination with natural conditions, socio-economic, policy factors and public will and other factors are used for determining the reclamation direction of the land to be reclaimed. The results show that the total evaluation area is up to 76.9828 hm^2, the area suitable for reclamation of forest land is up to 39.3712 hm^2, the area suitable for reclamation of arable land is up to 34.7471 hm^2, and the area suitable for natural retention and natural water accumulation to form the pit surface is up to 2.8645 hm^2. An index system of suitability evaluation of mine land reclamation is established.
