景观生态分类与制图浅议

本文在查阅分析大量文献和前人研究的基础上 ,对目前景观生态分类和景观制图作了详细的对比分析 ,认为景观分类需要结合实际区域现状 ,采用逐级分类的方法 ;同时利用 ETM遥感影像为数据源 ,以天山北麓为示范区.研制其土地利用土地覆盖变化的景观类型图。     

AN ILLUSTRATIVE STUDY ON LOCAL LANDSCAPEAND ITS LONG-TERM CHANGES BASED ON IKONOS AND HISTORICAL AERIAL PHOTO

Nowadays, the research works on landscape at fine scales using high-resolution images are uncommon.This research is based on the analysis of the combination of remote sensing data (1KONOS imagery acquired in 2002 and historical aerial photo taken in 1942). In the paper, the ecotopes in Qiujiadou and Xishao villages in Yixing City of Jiangsu Province in 1942 and 2002 were compared and landscape changes as well as the causes of the considerable changes were analyzed. It was found that the ecotope changes were at greater level in some aspects such as water surface and perennial vegetation coverage etc. This study at fine scale is globally significant for the rural areas, especially for the subsistence agricultural land, which occupies larger percentage in the earth. And it analyzes the structure of landscape based on a new landscape classification system--stratifications method.     

中国1∶100万景观生态制图设计

中国1∶100万景观生态图系借鉴国内外传统景观制图方法和制图规范,在遥感、地理信息系统先进技术的支持下,设计研制其制图方法、制图内容、样图和技术流程,同时提出初步的景观分类系统,为今后编制中国1∶100万景观生态图奠定基础。     

用地申请被否决之后……——修武县周庄国土资源所服务新农村建设纪事

"新农村建设是大事,改善群众的物质文化生活,给广大村民提供休闲、娱乐、健身的良好环境是好事,我们积极支持,但占用耕地建游园坚决不行,这是原则问题".修武县周庄国土资源所所长薛晨生这番话一出口,来递用地申请的五里堡村村委李主任满面春风的笑容不见了,铁青着脸甩手离开了国土所办公室,这是前不久发生在修武县周庄国土资源所的一幕.     

贯彻落实科学发展观为北海经济发展服务

党的十六届三中全会提出了"坚持以人为本,树立全面、协调、可持续的发展观,促进经济社会和人的全面发展"的方针.科学发展观,对如何进一步加强土地、矿产、海洋管理工作,促进经济可持续发展,建设和谐社会提出了新的更高的要求.贯彻落实科学发展观,管好用好国土资源,为北海经济发展服务,是北海市国土资源管理部门的重要职责.笔者就此浅谈一些个人的看法.     

为了红土地的崛起——百色市国土资源局真抓实干优质服务报告

2002年6月，国务院批准百色地区撤地设市。当年11月1日，百色地区国土资源局改为百色市国土资源局并正式挂牌。它的职能由此发生了重大变化，由原来的宏观协调指导转为容土地、地质矿产、测绘等各项业务为一体的综合管理。人员精简了，工作范围广了，工作量大了，工作任务更重了，而随着国家西部大开发战略实施的深入，特别是     

STUDY ON THE INTERACTION BETWEEN NDVI PROFILE AND THE GROWING STATUS OF CROPS

Daily and ten-day Normalized Difference Vegetation Index(NDVI) of crops were retrieved from meteorological statellite NOAA AVHRR images ,The temporal variations of the NDVI were analyzed during the whole growing season,and thus the principle of the interaction between NDIV profile and the growing status of crops was discussed,As a case in point,the relationship between integral NDVI and winter wheat yield of Henan Province in 1999 had been analyzed.By putting integral NDVI values of 60 sample counties into the winter wheat yield-integral NDVI coordination,scattering map was plotted. It demonstrated that integral NDVI had a close relation with winter wheat yield.These relation could be described with linear,cubic polynomial ,and exponential regression,and the cubic polynomial regression was the best way,In general ,NDVI reflects growing status of green vegetation ,so crop monitoring and crop yield estimation could be realized by using remote sensing technique on the basis of time serial NDVI data together with agriculture calendars.
