基于可视化的山西省土地压力测度及缓解途径研究

Research on Land Pressure Measurement and Mitigation Based on Visual Method

土地作为农业发展的基础和载体,同时面临经济建设和生态环境保护的需求.随着人类活动的加剧,土地面临着前所未有的压力.从农业发展、经济建设和生态环境保护三个角度,采用土地利用总体规划中期的现状数据与规划预期数据,对山西省土地压力进行科学测度,基于地统计学理论,对山西省土地压力空间分布格局进行可视化表达,进而分析成因并提出缓解土地压力的对策.结果表明:山西省土地压力具有明显的空间分异规律,土地综合压力指数呈团状和点状的分布格局,自北向南逐渐下降,中部局部地区略低于周边;耕地压力指数呈南北高、中间低,且东部略高于西部;建设用地压力呈中部高、四周低;生态用地压力呈由北向南逐渐递减的趋势.

Land was influenced by the economic construction and ecological environment protection as the basics of agriculture development,which was faced unprecedented pressure along with social economy construction.The land use pressure was measured scientifically,which using the present situation data and the planning demand data of the general land use planning,considering the factors of agricultural development,economic construction and ecological environment protection.The spatial distribution of land use pressure was analyzed visually based on geo-statistical theory in Shanxi province.Then the causes were analyzed scientifically and the countermeasures to alleviate of land pressure were put forward.The research results show that land utilization pressure index had obvious spatial differentiation regulations in Shanxi province.The comprehensive land pressure index decreased from north to south gradually,which present the distribution pattern of clumps and dot.The cultivated land pressure index present the characters of north-south high and central low,east region higher than west region slightly.The center was high and the sides were low of the construction land.The ecological land pressure decreased from north to south gradually.
