摘要
有色金属资源的开采与加工可影响城市土地利用和生态环境状况,协调土地利用与生态环境的发展关系对改变传统的城市土地利用模式,促进人与自然和谐发展具有重要意义。选取典型有色金属资源型城市——葫芦岛市建成区为研究区,以土地利用评价值和生态环境评价值作为定量评判指标,通过建立协调发展度模型,对2001—2009年葫芦岛市土地利用与生态环境协调发展类型及演进模式进行研究。结果表明:9a间葫芦岛市土地利用评价值由0.116 3提高至0.882 1,生态环境评价值由0.325 9提高至0.711 7;协调发展度由0.364 5提高至0.882 5,从濒临失调类土地利用滞后型模式演进为中级协调类生态环境滞后型模式。生态环境的建设与保护水平滞后于土地利用水平,成为制约葫芦岛市土地利用与生态环境高效协调发展的主导因素。
The mining and processing of the non-ferrous metal resources affect the urban land use and eco-environment situation.The coordination of development relationship between land use and eco-environment has an important meaning for changing the traditional urban land use pattern and promoting the harmonious development between human and nature.This article takes build-up area of Huludao City（the typical non-ferrous metal resources-based city） in Liaoning Province as the study area,selects the evaluating value of land use and eco-environment as the indicators,builds up the model of the coordinated development,studies the coordinated development type and evolving mode of land use and eco-environment of Huludao City from 2001 to 2009.The results showed that,the evaluating value of land use rose from 0.116 3 to 0.882 1,the evaluating value of eco-environment rose from 0.325 9 to 0.711 7;the coordinated development degree rose from 0.364 5 to 0.882 5,the mode changed from the brink of disorders and lag of land use to moderated coordinated and lag of eco-environment.The construction and protection of eco-environment lag behind land use,which proves to be the dominant factor restricting the effectively coordinated development between land use and eco-environment.
