摘要:

中共中央提出的“五化”发展战略有助于促进土地资源的可持续利用。鹤壁市作为河南省的粮食生产核心区同时又处于河南省中原经济区的发展之列，肩负着保证粮食安全和实现中部崛起的双重重担，基于“五化”视角对鹤壁市过去20年土地利用动态变化进行研究具有现实意义。文章使用包括RS和GIS在内的“信息化”手段，运用ENVI、ArcGIS及Fragstats软件方法，对鹤壁市建设用地基于“工业化与城镇化”、对耕地基于“农业现代化”、对林地基于“绿色化”进行具体分析。主要结论有：工业化与城镇化下，鹤壁市建设用地实现了扩张与集聚，城市建设向“一核双星”模式发展；农业现代化下，耕地资源丰富且变化日益趋向集中连片，但近年有减少趋势；绿色化下，鹤壁市由前10年的林地减少，变为净增加8558km2，但仍存在工程设施侵占的问题。为实现土地资源的可持续发展，建议应在未来利用中以节约集约为核心，以生态环境保护为主导对土地资源进行挖潜。

Abstract:

The Central Committee in China puts forward the development strategy of five modernizations which is helpful to promote the sustainable use of land resources.As one of the core grain producing area in Henan Province，Hebi City is in the list of Central Plains Economic Region at the same time and affords the double burdens of not only ensuring the food security but also realizing the rise of central china.Taking Hebi City as an example，this paper studied the dynamic changes of land use based on “industrialization”，“urbanization”，“agricultural modernization”，“greenization” and “informatization” which was called “five modernizations”.Using the RS，GIS，ENVI software，ArcGIS software and Fragstats software，it analyzed the change of construction land，agricultural land and forest land.The results showed that the construction land of Hebi City was expanded and concentrated，and the development mode of the urban construction was “one nuclear and double star”.At the same time，the rich cultivated land resources concentrated from 1993 to 2013 under the “agricultural modernization”.But with the effect of the rapid expansion of the construction land，the cultivated land resources had been reduced in the past 20 years，which become a big problem for saving the cultivated land resources.The forest land had a net increase of 8.558 km2，but there was still a problem of invasion.Finally，it suggested that it should take intensive conservation as the most important core，and protect the ecological environment as the leading point of using potential of land resources to realize the sustainable development of all kinds of land resources.
