基于水资源的国土空间规划下城镇规模预测OACSTPCD

Previously,the scale of urban planning and construction land was mostly a rough development mode of disorderly expansion,which took population growth and economic development into account,but not water resource utilization and protection.By studying the laws of natural population growth and industry-driven population growth,we established the dialectical relationship between water resource utilization and population growth,calculated the scale of regional population growth and the upper limit of population that could be carried by water resource in 2025 and 2035,and comprehensively determined the planned urban population.Combining with the national per capita construction land index,we calculated the total scale of planning land,determined the urban development boundary line,and comprehensively determined the reasonable scale of urban development in 2025 and 2035 by the upper limit of water resource and population development demand,so as to achieve the goal of high-quality development of"city by water".We applied this method into the urban development scale prediction of Gongbu Jiangda County in Tibet.
