Gradient Difference of Structure of Rural Construction Land in Loess Hilly Region: A Case Study of Yuzhong County, Gansu Province, China

Studying the differences in township gradient of rural construction land structures at microscale is beneficial for adjustment structure based on local conditions and differentiation, classification guidance scientific planning management land, improving level intensive use land. In this study, we took 268 administrative villages Yuzhong County Loess Hilly Region as research object conducted internal difference from two aspects: quantitative spatial layout. The main conclusions are follows: (1) distribution has significant connection with river road. county simple, large area uneven quantities between different types; (2) shape a patch complicated, high degree fragmentation. agglomeration not significant, there “east-west-north-south” space; (3) effect level. terms structure, closer to key towns central towns, more complex higher information entropy well equilibrium degree, lower dominant degree. Moreover, layout shows an upward trend fractal dimension, fragmentation separation when decreases.
