Abstract

Land as a scarce and non-renewable resources, is the material basis of human survival, but also has been a national land-use planning, protection and control of the main objectives. Based on China's densely's basic national conditions, \. This paper summarizes results of intensive land use from home and abroad on the basis of in-depth analysis of the socio-economic and natural Tianshui City land use status, the domain was constructed by the city land conservation and intensive use of the total target layer to land conservation and intensive use of agricultural land and construction land conservation and intensive use as a criterion layers to land investment intensity, land use intensity, land use efficiency, land use structure and layout and land use trends for the sub-criteria level, including 34 index layer of the city region land conservation and intensive use comprehensive evaluation index system . Using entropy method Tianshui overall level of intensive use of land conservation and dynamics analysis were evaluated, using factor analysis Tianshui agricultural land and construction land conservation and intensive use of spatial differences were evaluated. Tianshui City, land conservation and intensive use evaluation results show that overall, Tianshui City, the overall level of intensive use of land conservation status of comprehensive evaluation value of 0.7216, a low degree of over-exploitation phase. Tianshui City, economical and intensive use of agricultural land and construction land saving and intensive level of significant difference between the level of agricultural land intensive level (0.7443) and the construction of economical and intensive land level (0.6984) reached a low degree of over-exploitation stage and moderate conservation land for construction is nearing intensive use stage; guidelines on sub-layer, the land use intensity index score highest (0.1973) and the land use structure and layout indicator lowest score (0.1035), land use structure and layout to be further optimized. Tianshui City, land conservation and intensive use dynamic analysis showed that from 1999 to 2008 Tianshui City in land intensive and economical use of integrated level rising farmland integrated value and the construction land integrated values ??were significantly increased, including construction land intensive economical use enhance the level faster than agricultural land; land investment intensity index and land use efficiency index showed a significant upward trend in land use and land development trend intensity index index uptrend, but compared to the previous two indicators of change is not great, and the land use structure and layout decreased slowly. Tianshui City, land conservation and intensive use of space diversity results showed that agricultural land intensive Tianshui City, economical use of regional differences more obvious, located in the northern part of Qin'an, Gangu County high level of economical and intensive use, while the eastern part of the wheat plot area, water County Zhangjiachuan County intensive conservation and utilization level is relatively low. Tianshui City, economical and intensive utilization of construction land space quite different, the highest level of intensive Qinzhou District (0.96) and the lowest Qinan (-0.58) significant gap should increase efforts in tapping the potential of the internal space. Tianshui City, combined with the actual situation of use of land resources, the paper concludes with strengthening land conservation and intensive use of Tianshui City, countermeasures and suggestions.
