| 6. | Mankind appropriates about a quarter of what is known as the net primary production of the earth ( this is the plant tissue created by photosynthesis ) ? a lot , but hardly near the point of exhaustion 人类消耗了1 / 4的被称作地球主要净产出的产品(由光和作用产生的植物组织) ,虽然很多,但离耗尽还远得很。 |
| 7. | The simulated results of net primary production ( npp ) are similar to other ' s study . the annual , seasonal and daily change of npp can reflect the physiological characteristic of vegetation growing very well and has close relationship with climatological factors 年npp的模拟结果与国内的一些其它类似研究结果接近, npp的模拟结果能较好地反映出植被生长的生理特点npp的月变化、日变化及年际变化对气候因子有不同的响应。 |
| 8. | The net primary production of chinese terrestrial vegetation during 19821999 excluding 1994 because of missing data was estimated , and its spatio - temporal patterns were explored , based on the casa carnegie - ames - stanford approach model and using remote sensing imagery noaa avhrr and land spatial data of vegetation , climate , soil and solar radiation 基于地理信息系统和卫星遥感技术,利用植被气候和土壤等地面空间数据,应用casa模型估算了19821999除1994年间我国植被年净第一性生产量及其时空变化。结果表明: 18年间我国植被净第一性生产量呈增加趋势,平均增加速率为0 . 024pgca |
| 9. | In one side , the study may make the simulating model of climatology and land - biosphere more perfect , in the other side , the study will help to discover the real action of vegetation in the global carbon circle , which gives the more scientific method to estimate accurately biomass and net primary production ( npp ) of ecosystem and how much carbon in atmosphere absorbed by vegetation , to predict the possible impact of global climate change on terrestrial ecosystems , and to make scientific strategies for the global change 一方面可以为进一步建立更完善的模拟气候与陆地生物圈之间关系的数值模式奠定基础,另一方面可为探索植被在全球碳循环中的具体作用,正确地评估和预测全球气候变化对生态环境的可能影响,制定相应的政策提供科学依据。本文以寒温带落叶针叶林区为重点来进行试验模拟,研究植被对气候强迫响应的有效途径。 |
