摘要零河线所处的马关县地处云南省东南部，东与麻栗坡县相连，并与西畴县隔盘龙河相望，南与越南的老街、河江两省的箐门、新马街、黄树皮、猛康四县接壤，西南与红河州的河口、屏边两县毗邻，北与文山县交界。县城距省会昆明442公里，距州府所在地文山72公里，距中越边境线约20公里；距昆河铁路和等级公路102公里，距“衡昆”高速公路106公里，距麻栗坡县天保口岸130公里。地属温带季风气候，四季分明，年平均气温在13．6-14．7℃之间。该地区地面起伏，山丘连绵，属于山岭重丘区，但是矿藏丰富，矿产资源种类多、储量大，有锌、锡、铟等11类47种。生物资源也十分丰富，特别是药、食两用的草果种植历史悠久，规模较大。所以很有必要建一条功能稍微俱全一点的公路，来促进当地经济发展。68731

The total design specification
Maguan County which Linhe Highway located located in the southeast of Yunnan Province, East Malipo county and Xichou County connected, and across the Panlong River, the southern border with Vietnam street, river two, Jing door, Malaysia street, Huang Shupi, Meng Kang four county, southwest of Pingbian and Honghe Prefecture estuary, two adjacent to the junction of the North County, and Wenshan County. County 442 kilometers from the provincial capital of Kunming, is located 72 kilometers from the capital Wenshan, about 20 kilometers from the border between China and Vietnam; from Kunming Hekou railway highway and 102 kilometers away from the "Heng Kun" highway 106 kilometers, 130 kilometers away from Malipo County, Tianbao port. Belong to temperate monsoon climate, four distinct seasons, the annual average temperature between 13.6-14.7 degrees. The area is undulating and hilly, belonging to the hilly areas of the mountain, but rich in mineral resources, mineral resources of various types, large reserves, there are 11 kinds of zinc, tin, indium and other 47 kinds. Biological resources are very rich, especially medicine, edible strawberry cultivation has a long history, large scale. Therefore, it is necessary to build a highway with a little function to promote the local economic development.
