To congratulate on the tenth aniversary of China's Environment Remote Sensing Committee, Professor Chen Shupeng pointed out on the Symposium of Remote Sensing Developing Trend and Research Front in 1990s that remote sensing technique had been listed as national key project twice in the past ten years. Encouraging progress has been made since then. Remote sensing information has been popularized gradually in the applications of economic con- struction and national defense building up. New applied fields have also been developed and distinct social and economic benefits have been achieved. A new service trade of high technology and information has been preliminarily come into being. It has started to arouse attentions from the academic activities in both the Asian-Pacific region and the world.In the coming ten years during which Chinese government will implement its Ten-year Program, remote sensing technique has been listed as key project in the Eighth Five-Year Plan again. Professor Chen Shupeng has consulted with 32 professors and experts on the remote sensing developing trend in 1990s in China. Several major points can be concluded as follows.(1) The development and application of meteorological satellite information will reach its climax once again. Relatively sufficient preparation on theory, methodology and technology has been made in the past ten years; and successful experience on launching satellite Fengyun-1 achieved. The disadvantages needed to be avoided have also been found. Thus, in the coming ten years, as one of major information sources in environment remote sensing, meteorological satellite will play vanguard role in natural disaster monitoring, crop yield estimating and global environment change studying.(2) With regard to resource satellite remote sensing, the ground receiving station built up by China has achieved successful operation experiences, and developed and improved the function of. receiving data and images from various satellites. In 1990s, in the sky of the Asian and Pacific region, there will be five kinds of international remote sensing satellites, i.e., Landsat-7, MOS, JERS, SPOT and ERS-1. The information sources will be very rich. The resource satellite cooperatively built up by China and Brazil will also join them in the middle of 1990s. It is expectel to provide real time assurance for information source after the establishment of remote sensing information system on natural disaster monitoring and crop yield estimating.(3) Airborne remote sensing technique system has made great progress in the past ten years. Break through both on design and application of airborne imagery spectrometer, multiple polarized side-looking radar, microwave radiometer and light aircraft; and on all-weather, information transmission and digital image processing has been made. It will be got stable and continuous development in urban planning and management, mineral deposit and petroleum field seeking, manufactory site and power station choosing, and disaster preventing, etc. Especially, it will be used to meet the urgent needs for investment environment evaluation in open cities.(4) The equipment potentiality and technical progress made in the past ten years should be fully used in the key projects of the Eighth Five-Year Plan taking two stnategic targets, "natural disaster prevention and harnessing" and "crop yield estimation", as subjects so as to compose an integrated technical system with fairly intelligent level; and to be of functions of great storage capacity, real time transmission and quick processing.(5) To continue participating in the international cooperation program taking global study as target. To contribute active efforts to the Ten-Year International Disaster Reduction, the International Space Year and the International Geosphere-Biosphere Program, etc.

过去十年,随着卫星航空信息日渐丰富,作为国家重点攻关项目的遥感技术不断开拓了应用的新领域,初步形成了一个新的高科技信息服务行业。“八五”期间,遥感又列为重点项目,预期气象卫星信息的开发与应用,将会再次出现高潮。在资源卫星群星灿烂,航空遥感持续发展的形势下,需要充分利用现有设备潜力和所取得的技术进步,集中力量,研制大容量存储,实时传输和快速处理功能的智能化技术系统。这样才能适应防灾,估产为主要目标,并兼顾开放城市及全球研究的需求。

This research applied 1:250,000 national geographical database as a major information source and GIS as a basic methodology to investigate the spatial distribution pattern of the rural settlements of Yulin area in North Shaanxi. Many basic characteristics of how the distribution of the rural settlements is affected by both nature and economic factors are found by means of many GIS based data processing methods. The experimental results obtained in this study should be helpful for the urban and rural settlement reconstruction planning in this area.

本研究以地理信息系统为基本技术手段 ,以国家 1:2 5万基础地理数据库等数字信息为主要信息源 ,对陕北榆林地区乡村聚落的空间分布规律与区位特征进行了探讨。通过综合应用基于GIS的缓冲区分析、多层面的复合分析等空间分析方法 ,揭示了该地区乡村聚落的空间分布受自然条件与人为因素影响的基本特征。研究结果可望为该地区的城乡发展规划提供有益的借鉴资料。
