| 1. | The function of forest ecosystem and conservation strategy of gongbu nature reserve 工布自然保护区森林生态系统功能及保护对策 |
| 2. | Capacity analysis on the reconstruction of various agriculture eco - system in the erosion areas 侵蚀坡地重建几种不同农业生态系统功能分析 |
| 3. | Some social , economic and ecological problems had been occurred since the station was put into operation 为此,将河流生态系统功能与水电站对河流生态系统的影响相结合,研究电站对河流生态系统服务功能的影响。 |
| 4. | Indicators of assessment of ecosystem health can be divided into three groups : ecological features indicators , function indicators and social - human impact indicators 一级指标有三个,为生态系统特征指标、生态系统功能指标和社会人文影响指标。 |
| 5. | So we could connect composition and diversification of forest plant community with ecosystem function of biodiversity ? ontrolling on forest insect 这就把森林植物群落的组成、结构的多样化与生物多样性的生态系统功能? ?对森林害虫控制力有机地联系起来了。 |
| 6. | The tong - term tune bests of pinus yunnanensis management lead to bio - diversity decrease , diseases and insect pests damage , genetic degradation , and productivity decline 摘要长期以来,云南松的纯林经营使得生物多样性降低、林分稳定性变差、遗传品质退化、林分生产力下降,从而导致生态系统功能衰退。 |
| 7. | It defines the function and circulation of sustainable development eco - city system . the spatial framework of sustainable development eco - city is put forward and the rules and conditions of the spatial framework are discussed 根据城市生态系统功能和运行理论,对基于可持续发展的生态城市系统运行进行了定义,提出了基于可持续发展的生态城市的空间和时间运行体系。 |
| 8. | We propose to integrate the life strategy approach and trophic group classification to obtain a better understanding of nematode diversity and their functions , so as to use nematodes as effective bioindicators in farmland ecosystems 建议通过综合土壤线虫的生活史策略和营养类群等信息,深入了解其生物多样性和土壤生态系统功能,从而更好地发挥土壤线虫对农田生态系统变化的生物指示作用。 |
| 9. | Through the assessment of ecosystem health in the three distribute : haxi , maozang and dahonggou , we conclude that haxi > maozang > dahonggou in value of ecological features indicators ; haxi > maozang > dahonggou in total value of function indicators ; dahonggou > haxi > maozang in individual value of function indications ; maozang > haxi > dahonggou in value of social - human impact indicators 每个一级指标下又分为若干个二级指标,山地生态系统特征指标有11个二级指标;生态系统功能指标有9个二级指标;社会人文指标包括14个二级指标。景观格局指标也被引入生态系统特征指标中。 |
| 10. | Soil - ecosystem has done much with the stability of agriculture , recently the facts influencing the function of soil - ecosystem were not restricting in polluting from physical or chemical sources , the gm technic applying in agriculture not only made the pumping harvest in agriculture , but produced the more serious harm : transgenic bio - pollution 摘要土壤生态系统的功能是否正常直接关系到农业系统的稳定,影响土壤生态系统功能的因素已经不是局限在化学物理污染上了,农业转基因技术的应用,为农业生产带来新的增长点,为消除传统的化学物理污染的同时,也给土壤生态系统带来了更深刻,难以控制的影响因子:转基因生物污染。 |
