Said academician of Chinese Academy of science, Institute of remote sensing and Digital Earth Institute director Guo Huadong 21 in the afternoon when accepting a reporter to interview, the scientific research personnel using remote sensing aircraft for the first time in the Ya'an earthquake of magnitude 7 occurred in high resolution aerial remote sensing image, has been known as the earthquake monitoring area "isolated island" Baoxing county and surrounding area assessment work. At the same time, the Institute also actively promote the sharing of remote sensing data, image, video and data services for earthquake relief.
He said, Baoxing county and surrounding areas of remote sensing monitoring and damage assessment of earthquake disaster results mainly includes 4 aspects:
One is the Baoxing county roads severely damaged, analysis of damage on the county along the river near the village to village about 7 km road, a total of 14 road damage, damage length of about 500 meters.
Two severely damaged Baoxing County buildings, the damage rate of more than 60%. The main manifestations of destroyed buildings for local damage and roof collapse, many old houses and simple work shed; schools, government buildings had no obvious collapse phenomenon; some damage to housing for personnel to carry out on-site assistance, but there are still some damaged area waiting for rescue; part of the housing near the mountain collapse and rockfall threatening by.
Three is the earthquake and the surrounding areas of the county Baoxing landslides landslide, part of secondary earthquake disaster greater risk. In the next few days earthquake may be rainfall, especially to geological disaster alert residents around the landslide, mud-rock flow caused by potential secondary. Baoxing County surrounding found landslide of 38, many of the landslide covered roads, serious impact on traffic and disaster relief work.
Four is the surrounding farmland, woodland Baoxing County damaged lighter, which farmland damage rate of less than
2.5%, damage rate of less than 2%. Farmland and forest damage is mainly composed of secondary disasters caused by landslides, collapse.
Sharing in the remote sensing data, remote sensing of the earth by the Chinese Academy of Sciences has launched the two batch of disaster area before the earthquake, satellite data sharing. As of 21 days 15 when, the earthquake, civil affairs, traffic, land resources and Sichuan Province and other central ministries and local governments, real-time sharing of satellite, aircraft aerial remote sensing data 462G; including the United States, Australia, Japan, Ukraine, Hongkong, Ya'an earthquake, concern at home and abroad customers a total of 7638 people, through the network to download earthquake remote sensing data share 176G.
Guo Huadong, Institute of remote sensing of the Earth Institute researchers based on the digital earth platform, using high resolution aerial remote sensing image, and superimposed names, road, river of basic geographic information data, has 21 production release in earthquake area in Lushan County disaster monitoring and evaluation system, the evaluation report for earthquake relief to provide a series of real-time disaster.
"Remote sensing is one of the most effective means of sudden disaster monitoring and assessment." He said, the Chinese Academy of Sciences Institute of remote sensing of the earth the follow-up work, including relief, post-disaster damage assessment provides real-time and quasi real-time monitoring with remote sensing data, further monitoring of earthquake potential secondary disasters, and provide scientific data for the reconstruction after the earthquake location.
China News Agency reporters also learned from the Chinese Academy of Sciences, the Institute started in the Ya'an earthquake relief work, many research institute actively participate in: Psychological Research Institute launched the emergency action of psychological assistance, sent is stationed in Beichuan psychological aid station psychological aid workers and the psychological two experts to the disaster area to carry out psychological first aid; Shenyang automation research the ruins of the deformable robots, robot life detector, unmanned rotorcraft 3 robots to hurry to carry out disaster relief work; Dalian Institute of Chemical Physics offers more than 500 large capacity, high specific energy supply to the earthquake-stricken area in Ya'an, provide long time lighting, communications and other support for disaster relief.
中国科学院院⼠、中科院遥感与数字地球研究所所长郭华东21⽇下午接受记者采访时表⽰，该所科研⼈员利⽤遥感飞机在雅安7级地震发⽣后第⼀时间获取的⾼分辨率航空遥感影像，已完成被誉为震区“孤岛”宝兴县及周边地区地震灾害监测评估⼯作。

同时，该所还积极推动遥感数据共享，为抗震救灾提供图像、视频等数据服务。

他介绍说，宝兴县城及周边地区地震灾害遥感监测与灾情评估结果主要包括4个⽅⾯：
⼀是宝兴县道路损毁严重，对宝兴县附近⼤坪村⾄顺江村约7公⾥道路的损毁情况进⾏分析，道路共损毁14处，损毁长度约500⽶。

⼆是宝兴县城建筑物损毁严重，损毁率逾60%。

损毁建筑主要表现为局部受损和屋顶塌陷，多为⽼旧民房和简易⼯棚；学校、政府部门建筑未发现明显倒塌现象；部分损毁房屋已有⼈员开展现场救助，但仍有部分损毁区域等待救援；靠近⼭体的部分房屋受崩塌和滚⽯威胁。

三是宝兴县城及周边地区地震滑坡多发，部分滑坡存在较⼤的次⽣地震灾害风险。

今后⼏天震区可能会有降⾬，特别要警惕居
民点周边可能引发的滑坡、泥⽯流等潜在次⽣地质灾害。

宝兴县城周边发现滑坡体38处，其中很多滑坡体掩盖道路，严重影响交通及救灾⼯作开展。

四是宝兴县城周边农⽥、林地损毁较轻，其中农⽥损毁率不⾜2.5%，林地损坏率不⾜2%。

农⽥和林地损毁主要由⼭体滑坡、塌⽅等次⽣灾害引起。

在遥感数据共享⽅⾯，中科院遥感地球所已推出两批灾区震前卫星数据共享。

截⾄21⽇15时，该所与地震、民政、交通、国⼟资源和四川省等中央部委及地⽅政府，实时共享卫星、飞机⾼空遥感数据462G；包括美国、澳⼤利亚、⽇本、乌克兰、⾹港等在内，海内外关注雅安地震⽤户共有7638⼈次，通过络下载地震灾区共享遥感数据176G。

郭华东称，中科院遥感地球所科研⼈员基于数字地球科学平台，利⽤⾼分辨率航空遥感影像，并叠加地名、道路、⽔系等基础地理信息数据，21⽇已制作发布芦⼭县地震灾区灾情三维监测与评估系统，为抗震救灾提供⼀系列实时灾情评估报告。

“遥感是突发灾害监测评估的最有效⼿段之⼀。

”他表⽰，中科院遥感地球所的后续⼯作中，包括将为灾后救援、灾情评估提供实时和准实时遥感监测数据，对震区潜在次⽣灾害进⼀步开展系统监测，为灾后重建选址提供科学数据等。

中新社记者当天还从中科院获悉，该院全⾯启动雅安地震抗震救灾⼯作后，众多研究所积极参与：⼼理研究所启动⼼理援助应急⾏动，派出正驻扎在北川⼼理援助站的⼼理援助⼯作者和⼼理所两名专家赶赴灾区开展⼼理急救⼯作；沈阳⾃动化研究所废墟可变形搜救机器⼈、机器⼈化⽣命探测仪、旋翼⽆⼈机3款机器⼈急赴灾区开展救援⼯作；⼤连化学物理研究所向雅安地震灾区提供500余台⼤容量、⾼⽐能量电源，为灾后救援提供长时间照明、通讯等保障。
