村域尺度土地利用现状分类体系的构建与应用 ——以山东禹城牌子村为例

随着LUCC到GLP研究的不断深入,我国空心村土地整治实践的相继推进,以及高分辨率遥感数据的陆续产生,深入开展村域尺度的土地利用调查与评价研究具有迫切现实需求,而构建村域尺度土地利用现状分类体系则是支撑村庄土地利用用地调查与评价的重要前提与关键。参考《土地利用现状分类》国家标准(GB/T21010-2007),构建了基于0.25m分辨率中科高清遥感影像的村域尺度土地利用现状分类体系,并在山东省禹城市牌子村进行了实际应用。构建的基于高分辨率遥感影像的土地利用现状分类体系,不仅准确反映了牌子村的土地利用结构及其用地特征,而且还测算出该村所具备的土地资源整治潜力,取得了良好的实际应用效果。基于0.25m高分辨率遥感数据所构建的村域土地利用现状分类体系有据可依,简单易行,成果明确。研究成果可直接为我国村庄特别是空心村土地综合整治潜力的调查与评价提供技术方法的有益参考和有力支持。

Construction and application of land use classification system on village scale: A case study of Paizi Village, Lun zhen,Yucheng City,

With the further research from LUCC to GLP, the initiation of the land regulation of hollow villages, and the successive creation of high resolution remote sensing images, it is practically demanded to carry out the land use investigation and estimation study on village scale. As the village is the most basic administrative unit, village-scale land use can be considered the most basic unit of regional land use. Current land use is divided into six categories: cultivated land, forest land, grassland, water body, construction land and unutilized land, which is the method commonly used in existing research into land use in China. A village, especially the homestead, leisure areas, and ponds inside a village, is considered as one type of land use rural residential land. As a result, the land use structure of a village is undoubtedly concealed and attains no attention. This caused China's severe shortage of information related to village-scale land use in a long period, which has also become a major blind zone in China's land use management and research. With the implementation of "hollow village" consolidation policy in China and the presence of high-resolution remote sensing data, especially as the strategy of new countryside construction goes further, it is imperative to fill in gaps in research of village-scale land use. Constructing the land use condition classification system on village scale should be the premise supporting the land use investigation and estimation. Referring to the Land Use Condition Classification for National Standard of the People's Republic of China (GB/T21010-2007), and based on 0.25 m high resolution remote sensing images, this paper built the land use condition classification system on village scale, which was applied in Paizi Village of Yucheng City, Shandong Province. The land use classification system based on 0.25 m high resolution remote sensing images constructed by this paper not only shows land use structure and its characteristics in Paizi Village, Yucheng City, but also explains the potentiality of land consolidation in Paizi Village, which obtained a good practical application result. This paper would provide beneficial experience and reference to land resources investigation and regulation on village scale.
