他介紹了巴西的生物柴油計劃,包括扭轉巴西北部亞馬遜地區和東北部乾旱地區落後的農業,以可持續的生產方式替代短期的生產方式,並提到巴西亞馬遜地區有約2億公頃被砍伐后正在退化,有可能在這些土地上種植當地的產油作物,形成一個產能可以供應整個歐盟生物燃油需求的能源作物林。The ephemerals is a kind of plant starting its new living period using the melting snow water in the early spring. they make use of melting snow water and spring rainwater under certain temperature to grow, then they will finish the life history quickly before hot summer comes
早春短命植物是一類生長在乾旱區,以早春融雪水啟動其新的生活周期,利用融雪水及春季雨水提供的土壤濕度和一定的溫度生長發育,在炎熱夏季來臨之前迅速完成生活史的一年生草本植物。This study run through the basic idea of ecoregional approach methodology and systematic design by integrating agronomy, ecology, environmental economics, resource economics and maths. the study methods included macro - and micro - analysis, qualitative and quantitative analysis, theoretical and case study, statistical analysis and model simulation and so on. resources shortage and environmental pollution casued by intensive agriculture were examined for a specific suburban area shunyi district beijingissues were systematically analyzed including landuse changes, landuse driving force, water - limited yield simulation with wofost model, ecological, environmental and economical analysis of landuse, as well as optimizing pattern of landuse with rcsadss model
本研究立足於生態區域法的基本思路,採用系統設計的思想,通過農學、生態學、環境經濟學、資源經濟學、數學等多學科的交叉與融合,宏觀與微觀、定性與定量、理論與實證研究等相結合的方法,運用統計分析、模型模擬等技術手段,在大量調研基礎上,針對目前大城市郊區農業用地中存在資源短缺、環境污染等問題,以北京市順義區為典例,從土地利用現狀與動態、驅動力、 wofost模型產量模擬、生態環境經濟分析及種植業結構優化模式等方面進行了系統研究,獲得如下研究結果: ( 1 ) 2002年順義區的土地利用仍以農業用地為主,耕地、園地、林地和牧草地之和占總土地面積的56 ,農用地中糧食作物仍佔43 。In a short time, it is not very obvious that the vegetation grows with the temperature relation ; the precipitation and vegetation of salt pond district grow and present obvious positive correlation, it is a main restriction factor of growth of vegetation ; the lagging effect exists in the impact on vegetation of change of precipitation, mainly reflect it on the amount of degree, vegetation height and living beings covered of the vegetation
結果表明:在大時間尺度上,氣溫與植被生長呈負相關;在短期內,植被生長與氣溫關系不很明顯;降水與鹽池地區植被生長呈現明顯的正相關,是植被生長的主要限制因子;降水的變化對植被的影響存在滯後效應,主要體現在植被蓋度、植被高度和生物量上。The velocities of growth in shrubs were different in different sand fixing region. the growth of plants in the sand fixing region with a shorter time were faster than that with a longer time. this maybe directly resulted in the difference of the density and coverage of shrubs
不同年代固沙區灌木植物的生長速度各不相同,沙地固定時一間短的樣地內灌木植物的生長較快,這可能直接導致不同年代固沙區灌木植物密度和蓋度的差異。分享友人
