摘要:
毕节试验区属典型的生态环境岩溶脆弱区，山高坡陡，宜耕地资源严重不足，石漠化严重。2008年在全国石漠化严重的8省（区、市）启动实施了100个县的石漠化综合治理试点工程，其中毕节地区8个县市全部被划为治理示范点。研究以石漠化严重的毕节试验区为例，选择与石漠化最为密切的自然干扰因子、社会干扰因子和石漠化景观格局因子，构建岩溶地区土地质量评价指标体系。选用熵权灰色关联法，对毕节试验区8个县市进行土地质量综合评价。结果表明：毕节试验区土地质量水平从高到低的顺序是威宁县>金沙县>黔西县>毕节市>赫章县>织金县>大方县>纳雍县。土地质量水平较好的是威宁县和金沙县；土地质量水平一般的为黔西县、毕节市、赫章县、织金县、大方县和纳雍县。为生态环境质量评价和退化土地的生态恢复提供一定的借鉴意义。
Abstract:
Bijie experimental area is one of the wildly distributed Karst place, where mountain is steep, land is rare, and rocky desertification is serious. In 2008, we implemented the rocky desertification control project in a hundred counties, and the eight counties of Bijie experimental area among them. Taking the Bijie experimental area as the case study, selecting the most closely influencing factors, we established the land quality indicator system. Based on the Entropy and Gray Correlation Method, we made the land quality evaluation. The result indicates that the sequence from good to badness is followed by Weining, Jinsha, Qianxi, Bijie, Hezhang, Zhijin, Nayong. Weining and Jinsha fall into good level, the rest of the counties are more average. The paper provides the correct method to land quality evaluation and assessment of the ecological restoration.
