一支由专业登山队员、科考人员、测绘专家、后勤保障人员和森林警察近百人组成的登山科考队，今天上午9点从大邑出发，徒步上行4天后冲顶位于西岭雪山的“成都第一峰”苗基岭。此次“穿越西岭原始森林攀登成都第一峰”活动由国家林业局森林公园管理办公室、四川省林业厅、成都市人民政府主办，大邑县人民政府承办，

　　活动预计持续12天。登山科考队员从大邑出发，经中嘴、黄水河，到达金鸡峡后徒步上行4天至冲顶营地。其间，除了要对西岭雪山震后地质植被变化情况进行考察外，测绘专家们还将用测量珠峰高度的方法，首次实地测绘成都之巅的精确高度。本报记者刘建作为副队长带队参加。

　　测珠峰方法量成都之巅

　　“西岭雪山距离汶川地震中心很近，地震对它造成了哪些变化？”资料显示，成都市行政区域内的最高峰为海拔5364米的西岭雪山主峰苗基岭（又名大雪塘）。

　　2002年成功登顶苗基岭的刘建介绍，5364米是主峰苗基岭的高度，但主峰上还有3个海拔高度相差不超过10米的山峰。成都市勘察测绘研究院总工办副主任邹仁均说，这是首次对苗基岭进行实地测绘，测量地震后成都第一峰的精确高度。“这次实地测绘和2005年中国珠峰测量登山队员测量珠峰的方法相同。测绘仪器也是目前世界上最先进的。”

　　邹仁均说，部分工作人员已在崇州鸡冠山森林公园、大邑西岭镇、小沟和苗基岭大本营设立了外围观察点，安装了高精准人造卫星系统GPS接收机。测绘人员登顶成功后，同时启动7台GPS进行测绘。“7组数据都接收到了才是成都第一峰的精准高度，力争误差在30厘米内。”

　　防通讯中断 带信鸽上山

　　因为担负着数项科考任务，登山科考队准备了笔记本电脑、海事卫星电话等通讯工具，但西岭雪山原始森林的地形相当复杂，进入深山后，手机、网络等信号相当不稳定，有队员建议不如带几只信鸽登山，出现通讯中断就飞鸽传书。于是，登山科考队马上联系大邑县信鸽协会，借出4只信鸽。

　　“都是得过奖的优良国血鸽，每只都有700公里以上的飞行纪录。”大邑县信鸽协会严会长准备了5斤细粮，“瓜子、花生、豌豆、苞谷，每只鸽子每天不能超过一两。”严会长说，因为山上气温低，还增加了能稳定鸽子体温的饲料“火麻子”。

　　信鸽飞行时速约70公里，西岭雪山到大邑县城的直线距离有100多公里。严会长介绍，天气晴好的条件下信鸽放飞后1个半小时就能飞回驻地，低温天气下飞行时间也不会超过2小时。“就怕遇到鸽子的天敌老鹰，只有看运气了。”登山队员将把相同的资料存放在两张数据卡上，每次同时放飞两只信鸽以防万一。

One by professional climbers, expedition staff, mapping experts, logistics personnel and forest police nearly a hundred-member mountaineering expedition team, today starting at 9 am from Dayi, walk up four days after the hoisting Xiling Snow Mountain is located in the "Chengdu first peak" Miocchi Ridge. This "climbing through the forests, Chengdu Xiling first peak" activities by the State Forestry Administration, Forest Park Management Office, Forestry Department of Sichuan Province, Chengdu People's Government hosted Dayi County People's Government contractors,

Activity is expected to last 12 days. Mountaineering expedition team from the start Dayi through the mouth, Yellow River, to reach Rooster Gap 4 days after the walk up to the hoisting camp. In the meantime, in addition to post-earthquake on the Xiling Snow Mountain geological changes in vegetation cover in the province, the surveying and mapping experts will also be the method of measuring height of Mount Qomolangma, the first time the summit of the field mapping the precise height of Chengdu. Liu Jian, vice captain as a reporter led to participate.

Method of measuring the amount of Chengdu, the summit of Everest

"Xiling Snow Mountain from the Wenchuan earthquake center very close to the earthquake caused it changed?" Data show that the peak of administrative regions in Chengdu 5364 meters above sea level peak Miocchi the Xiling Snow Mountain Ridge (also known as snow Tong).

2002 a successful ascent Miocchi Ling Liu introduction is 5364 meters high peak Miocchi Ridge, but there are still three main peak altitude difference of no more than 10 meters in the mountain. Survey of Chengdu Institute of Surveying and Mapping, deputy director of Zou chief engineer office both said that this is the first time Miocchi Ridge field mapping in Chengdu after the earthquake measuring the exact height of the first peak. "The field mapping and measurement of in 2005, Everest Everest climbers measured the same way. Survey Instrument is currently the world's most advanced."

Zou said that his staff has been part of the work Chongzhou Jiguanshan Forest Park, Dayi West Zhen, small ditch and shoot set up camp outside the base range observation point, the installation of satellite systems for high-precision GPS receiver. After the successful ascent mapping personnel, while started seven Taiwan GPS mapping. "7 sets of data are received to the first peak in Chengdu is a high degree of precision, and strive to within 30 cm error."

Anti-a breakdown in communications with a homer into the mountains

Because a number of expedition charged with the task, mountaineering expedition team prepared a notebook computer, marine satellite telephone communication tools, but the jungle terrain Xiling Snow Mountain is a complex into the mountains, the mobile phone network signals rather unstable, there is carrier pigeon with a few members have suggested mountain climbing, there was a communication disruption on the IP Messenger. As a result, mountaineering expedition team immediately contact Dayi County homing pigeon association, lending four homing pigeons.

"Are award-winning fine country pigeon blood, each have more than 700 km of flight records." Dayi County, Yan, president of Pigeon Association, prepared a 5 pounds flour and rice, "melon seeds, peanuts, peas, corn, each pigeon for every can not be more than 12 days. "Yan president said that because of the mountains low temperature, but also increased the temperature of the feed pigeons can stabilize the" fire pock. "

Pigeon flying at a speed of about 70 km, Xiling Snow Mountain to the straight-line distance of Dayi county more than 100 kilometers. Yan, president of introduction, under the conditions of fine weather after a pigeon and a half hours flying will be able to fly back to the resident, cold weather, the flight time will not exceed 2 hours. "Afraid of the enemies encountered in pigeon eagle, only to see luck." Climbers the same information will be stored in two data cards, two for each pigeon flying at the same time just in case.
