A SURVEY OF VILLAGE LAND USE POTENTIALITY BASED ON 0.25M RESOLUTION IMAGES——EXEMPLIFIED BY 12 VILLAGES IN JUYE COUNTY,SHAN DONG PROVINCE
利用0.25米高分辨率遥感影像，量化山东省巨野县12个村庄的土地类型，计算短期和长期土地利用潜力，发现平均短期潜力为68.2亩，占村庄总面积的3.69%，且潜力不仅存在于宅基地，还存在于空闲地、坑塘等类型。
Survey of village land use potentiality is an important part of the integrated regulation of villages.Finding out the land use potentiality of the village scale is of great significance to holding the area of arable land in China above the red line of 1.8 billion mu,promoting the construction of new countryside,and pushing forward the balanced development of rural urban and rural areas.In this study,we have applied the high resolution remote sensing images with a resolution of 0.25m to 12 villages in Juye County of Shandong Province.By quantifying the village land types,we have calculated the land use potentialities in the short term and in the long term.The survey has indicated that the average land use potentiality of the 12 villages in the short term is 68.2 mu,accounting for 3.69%of the whole area of the villages.The composition of the short-term land use potentiality differs from area to area;the long-term land use potentiality can be measured by two standards: one is land use potentiality per household,and the other is land use potentiality per person.The land use potentiality per household is larger in quantity and proportion than the land use potentiality per person,and it exceeds the standard a lot.Meantime,we have discovered that the land use potentiality exists not only in rural homestead,but in other land types such as unoccupied land and pit-ponds.The vacancy and abandonment of rural homestead is only a surface phenomenon.This research result can offerdirect reference to the investigation and evaluation of land consolidation potential on village scale in China.
