简介：一、地质调查装备支撑地质调查转型升级1.地质调查研究对象和服务方向的转变,给装备建设提出新的更高要求新时代地质调查服务方向发生了重大转变,从服务单一门类矿产资源调查向服务包括矿产资源在内的多门类自然资源综合调查转变。新时代地质调查研究对象发生了根本转型,从矿产资源调查转型为山水林田湖草多种自然资源综合调查,从传统地质科学理论向地球系统科学理论转变。地质调查装备也将相应地进行转型。

简介：本文阐述了中国亚热带的6个基本特点，亚热带北界和南界的划分问题，生态过渡带和亚热带划分的方法论，综合区划研究的必要性与重要性，以及尚需深入研究的若干重要自然地理界线问题．认为中国的亚热带从广义上说也是一个生态过渡带．深入研究中国亚热带形成的机制及其成因和演变趋势，将有利于整个亚热带的区域可持续发展．目前亚热带划分所用的指标比较初始、简略，亚热带的东部与西部所采用的指标也不完全一致，还需要经过艰苦的探索，提出一个既能反映客观实际，又能与国际研究接轨的较好方案．在亚热带的划分中需要加强新技术和新方法的应用．

简介：据首次全国湿地资源调查统计,我国湿地资源十分丰富,总面积为3848.55×104hm2,湿地陆生野生动物共25目、75科、724种,野生高等植物有225科815属2276种,划分为7个植被型组,16个植被型,180个群系.我国湿地正面临着来自人类的巨大威胁,如人类对湿地的盲目围垦和改造、湿地环境污染、生物资源的过度利用等,导致自然湿地数量持续减少、湿地生态功能退化乃至丧失,已难以保证所在地域生态平衡的需求.根据我国湿地面临的威胁和问题,近期应加强湿地保护立法和管理机构建设,并尽快实施.

简介：人类对自然界的认识过程总是由浅入深循序渐进的。回顾过去，中国黄土成因经历了从“水成”到“风成”这样一个曲折的认识过程。通过分析黄土成因争论的历程，得到如下启示：1）过去的黄土成因争论源于人们不认识黄土层中的古土壤，因此识别地层中古土壤对重建古地理环境具有重大意义。2）水平层状地层并非都是水平沉积层理，也有可能是古土壤发生层次，具有水平层理的沉积地层则可能意味着在水中沉积形成，而古土壤层则是在地表环境形成。3）古土壤层的特点是古土壤层具有土壤发生层次，因此各层次之间一般呈现为渐变特征。而沉积地层通常具有明显的顶部和底部，显示着截然变化。4）在总结新生代古土壤特点的基础上，重新认识更老地层的古地理环境，发挥古土壤在研究地层成因、重建古气候等方面的作用。

简介：湿地被称为"地球之肾",具有独特的生态结构与功能.中国湿地面积约占全球湿地面积的10%,但近年来湿地面积逐渐萎缩,已造成了极为严重的生态恶果.因此总结以往湿地研究成果,确立包括遥感在内的各种湿地信息提取方法,形成包含各种湿地信息的湿地数据子库和管理操作这些数据的湿地信息系统,并确立湿地信息的共享与发布机制,从而加快湿地科研步伐,成为湿地与遥感科技工作者共同关注的问题.WebGIS技术是GIS融合Internet技术发展起来的新技术,具有对大批量数据进行有效的分析管理和快速的查询检索功能.基于WebGIS技术的中国沼泽信息系统的建立有效地满足了湿地科研和开发保护的需要.
