So exploring the connotation and service mechanism of ecosystem service functions and analyzing the trend of development and evolvement of ecosystem under the condition of human beings effect are the foreland task of ecology and eco - economy . they hold out and protect ecosystem service function . accordingly , they promote the sustainable development of it 因此,探索生态系统服务功能的内涵与服务机制,分析和探讨人为影响下生态系统发展演化的趋势,从而更好地维持和保育生态系统服务功能,促进经济社会的可持续发展已成为当前生态学和生态经济学界研究的前沿课题。
Combined with landscape pattern analysis , this report draw a conclusion as follows : because people ' s knowledge about ecosystem service function is not enough , people pay attention to utilizing ecosystem , whereas they make light of building and management , which increase ecosystem fragmentation degree and decrease service function 结合景观格局分析得出以下结论:由于人们对生态系统服务功能价值的认识不够,长期以来,人们重利用,轻建设,轻管理,使得生态系统破碎化加剧,服务功能降低。
The contents of its research primarily includes the completes with the stability of district land ecosystem ; the land ecosystem health diagnosis ; the sustainable of land ecosystem service function ; the define and judgment of the threshold of land equilibrium expectation , the continuous of process of land ecosystem ; the monitoring and estimate of condition of land ecosystem ; the management of land ecosystem 其研究内容主要包括区域土地生态系统的完整性和稳定性;土地生态系统健康诊断;土地生态系统服务功能的可持续性;土地生态平衡期望值的设定及重要阈值的判定(变化的允许范围) ;主要土地生态过程演化的连续性、演化状况的监测以及演化的预测和预警;管理和维护的调控对策等。
The current studies focus in developing multi - scale data - model fusion approaches and new generation of ecosystem models for simulating cross - scale interactions , understanding and quantifying impacts of climate and land use changes on terrestrial ecosystem productivity and water , carbon and nitrogen cycles , and assessing changes in ecosystems services , carrying capacity and sustainability 目前的研究工作集中于:发展多尺度的数据模型融合方法,建立能够进行跨尺度机理模拟的新一代生态系统模型;认识气候和土地利用变化对区域和全国陆地生态系统生产力和水碳氮循环变化的影响;评估生态系统服务功能、承载能力和可持续发展能力。
What ' s more , looking from the service functions of natural ecosystem , it also makes the idea of natural ecological assets enter the strategic decision of wuxi city development , through assessing the economic value quantitatively for the four types of systems and showing different service functional abilities of ecosystem in the form of monetary value , so that it gives the wuxi city an important guidance for its sustainable development 并从自然生态系统服务功能角度,对这四类生态系统进行经济价值量化评,以货币价值的形式表达不同的生态系统服务能力,使自然生态资产理念进入无锡市城市开发决策视野,对无锡城市可持续发展建设进行有效的指导。
Based on the characteristics and connotation of forest ecosystem services , the physical and value assessment methods , including market value method , shadow engineering price method , production cost method , opportunity cost method and administering expenditure method , were used to evaluate forest ecosystem services in yashushan natural reserve 摘要根据福建宁化牙梳山自然保护区森林生态系统的特征和森林生态系统服务功能的内涵,采用物质量和价值量相结合的评价方法,使用市场价值法、影子工程价格法、生产成本法、机会成本法、治理费用法等定量评价了宁化牙梳山自然保护区森林生态系统服务功能经济价值。
