    摘要:

    农牧交错线与胡焕庸线基本重合,其数据具有良好的稳定性。近30年,相互独立的4次人口普查都显示,该线西北57%的国土面积承担着5.7%的人口。本研究基于新思路和GIS平台将胡焕庸线投射到农牧交错带后,可生成农牧交错线。研究结果为首次用GIS表达的农牧交错线,始于黑龙江省黑河市瑷珲区的中俄界河,经黑龙江、内蒙古、河北、陕西、宁夏、甘肃、青海、四川和云南等9个省(区)的84个县(市、旗),终于云南省腾冲市西南的中缅边界,总长度约5 136 km;该线西北侧53.3%的国土面积承担着16.8%的人口,东南侧46.7%的国土面积承担着83.2%的人口。本划分结果更准确,更具有生态和社会意义,有利于将来国家各种规划的制定和执行。调研中的西部引水工程红旗河工程,其两侧连片的绿洲有20多万km2,预计至少可开发出3亿亩良田,提供2亿人口的移民空间。综上所述,红旗河工程若实施,中国西北部的人口,将从现在不足0.8亿人(总人口的5.7%)剧增到近3亿人(总人口的21.4%),传统的农牧交错带将发生重大位移,胡焕庸线这条延续了百年的所谓人口密度线也将随之改变。

    Abstract:

    The farming-pastoral ecotone (line) basically coincides with the Hu Line,and its data has good stability.In the past 30 years,four separate censuses have shown that 57% of the land northwest of the line is home to 5.7% of the population.In this study,based on new ideas and GIS platform,Hu Line line was projected to the farming-pastoral ecotone,and the farming-pastoral line could be generated.This study showed that the agro-pastoral line which was expressed by GIS for the first time begins at the Sino-Russian border river in Aihui District,Heihe City,Heilongjiang Province,and passes through 84 counties,cities and streamers in 9 provinces (districts),including Heilongjiang,Inner Mongolia,Hebei,Shaanxi,Ningxia,Gansu,Qinghai,Sichuan and Yunnan province,and finally reaches the Sino-Myanmar border in the southwest of Tengchong City,Yunnan Province,with a total length of about 5136 km.The 53.3% of the land on the northwest side of the farming-pastoral line bears 16.8% of the population,and 46.7% of the land on the southeast side bears 83.2% of the population.The above results are more accurate,having more ecological and social significance,and is conducive to the formulation and implementation of various national plans in the future.The proposed Hongqi River project,with more than 200,000 km2 of continuous oasis on both sides,could develop at least 20 million/km2 of fertile farmland and provide space for the migration of 200 million peoples.After the completion of the Hongqi River project,the population of northwest China will increase from less than 80 million (5.7% of the total population) to nearly 300 million (21.4% of the total population).The traditional farming-pastoral ecotone will be greatly displaced,and the HU Line which had lasted for 100 years,so-called population density line,will also change accordingly.
