中文摘要:

本文利用气象卫星(NOAA/AVHRR)遥感技术和地理信息系统技术对晋陕蒙接壤地区1988年7月至1993年9月,六年生长季节的植被盖度进行了动态监测研究,并对同期监测地上生物量的方法进行了初步的探讨。对应用气象卫星植被动态监测的理论基础、方法及技术进行了系统的研究,并指出动态监测的目的不仅在于研究植被的短期变化,更重要的是揭示引起这种变化的成因的不确定性,从而分清引起变化的主要因素。本文主要的研究内容及提出的观点如下: 1、气象卫星NOAA/AVHRR资料对植被进行时空动态监测的理论、目的及意义。 2、气象卫星植被动态监测的技术方法研究。1主要包括:各种资料的预处理、实时植被景观类型的区分、动态监测分区单元划分的理论和依据、动态监测模型的建立(遥感模型和地学模型)及建立的原则。并得出NOAA/AVHRR资料预处理的质量及各种资料间的配准是制约植被动态监测准确性的瓶颈。 3、1988-1993年晋陕蒙接壤地区植被盖度监测的研究及植被盖度时空变化分析。研究表明:晋陕蒙接壤地区植被盖度的时空变化变率较大,且东西分异十分明显,与降水等值线分布基本一致。年内最高植被盖度一般出现在8月或9月。 4、从整个研究区域来说,植被盖度的变化还是受降水控制的,人为活动只对局部地区起作用,引起植被盖度的升高或降低。另外,本文根据多年平均植被盖度与多年年平均降水的关系,把晋陕蒙接壤地区划分为三类地区,即: (1)、植被盖度与降水贡献一致 (2)、植被盖度高于降水贡献 (3)、植被盖度低于降水贡献 从而对影响植被盖度变化的成因进行了初步分析,进一步区分出了晋陕蒙接壤地区植被盖度变化主要受降水等自然因素控制和主要受人为活动控制的地区。 本文为国家八五攻关资助项目

外文摘要:

In this paper, NOAA-9 and NOAA-11 data with a 1.1 km spatial resolution from July 1988 to September 1993 have been processed to dynamically monitor the vegetation canopy of growing season in Jinshanmeng region by using the technique of meterological satellite and GIS. Meanwhile the method of dynamic monitoring biomass procduction on the ground have been researched preliminarily. By using meterological satellite information, the theory, method and technique of dynamic monitoring have been researched systemically.After that, we indicated that the most important. purpose of dynamic monitoring is not only to research the short time variation of vegetation, but also to reveal the indefinitive of causes which lead to that variation. the main research contents and conclusions include as follow: 1.The theory, purpose and important of vegetation dynamic monitoring using meterological satellite informations(NOAA/AVHRR). 2.Some research works were carried out into the technical method using meterological information in vegetation dynamic monitoring Mainly include:preprocessing of different kinds of informations、deviding vegetation landscape type inal time、 the theory and basis of deviding dynamic monitoring unit、 the construction of dynamic monitoring model ( remote sensing model and geographical model)and the principle of the construction. It has been indicated that the qua1ity of information (NOAA/AVHRR)preprocessing and the adjustment of different informations is the limited factors which prevents the accuracy of vegetation .dynamic monitoring. 3. Vegetation dynamic monitoring research and the space-time changes of vegetation canopy from 1988 to 1993 in Jinshangmeng region Research indicating: the change rate of vegetation in space-time is greater in Jinshanmeng region, the differences between and east west are obvious and mainiy accord with the distribution of the precipitation isopleth. the highest value of vegetation canopy often occurs in August or September every year. the whole region, the vegetation canopy is Considered from by precipitation. Human activities only act control on some areas the vegetation canopy increase decrease. In and cause to or . vegetation according to the relation between the addition, mean canopy value of years and the mean precipitation of years, three kinds of areas were devided as follow: (1). The Value of vegetation canopy equals the contribution of precipitation (2). The Value of vegetation canopy higher than the contribution of precipitation (3). The Value of vegetation canopy lower than the contribution of precipitation and we preliminarily analysised the causes which affected variation of vegetation canopy, then dedived Jinshanmeng region into two kinds of areas. One is controled by natural factors such as precipitation, etc. Another is controled by human activities.
