The results are as follows : the differences of microorganism quantity among different type of soil is the significant , so are the enzyme activity and soil nutrient 与健康林相比,出现生长衰退林地土壤样品的养分指标、微生物和酶活性均有显著程度的降低,表明土壤地力已出现严重衰退。
( 3 ) compared to young stand of the first rotation of larix olgensis , activity acidity ( ph value ) , organic matter content , humus component content , moisture , and total porosity in rhizosphere soil of the young stand of the second rotation of larix olgensis decreased ( 3 )二代落叶松幼龄林与一代落叶松幼龄林相比,根际土壤活性酸( ph值) 、有机质含量、腐殖质组成、土壤水分含量和总孔隙度降低。
The founder of the shop was lin hsin - chu , and it is now run by the second generation , in the person of lin hsiang - lin , who is preparing to pass it on to his son lin huang - yi . three generations , all coopers , have kept this physically decaying old shop as spritely as an infant 林田桶店的创始人为第一代的林新居,第二代林相林也是目前的经营者,准备交棒给儿子林煌一,三代皆以制桶为业,守著破旧老店却甘之如饴。
The study indicates that digital photographic aerial photo , ikonos ( panchromatic and multi - spectral ) , spots ( panchromatic and multi - spectral ) and the emerging map of spot4 ( panchromatic ) and etm can all be used in the forest management inventory , whereas etm ( including tm ) or the emerging map of etm and spot4 ( panchromatic ) can be used to investigate forest resources and draw maps in the mountain area of better forest aspect , when the first three remote - sensing sources can be used in the investigation of urban resources and the demand on detailed investigation is higher or the map - drawing of 10 , 000 ratio scale 研究表明:数字航空像片、 ikonos (全色和多光谱) 、 spot5 (全色和多光谱) 、 spot4 (全色)与etm的融合图都可以应用于森林资源二类清查,而前三种遥感信息源也适用于城市资源调查以及要求调查详细程度更高或1 : 1万比例尺的制图,在林相较好的山区,可应用etm (包括tm )或etm与spot4 (全色)的融合图进行森林资源调查与制图。
Abstract : through a study on soil aggregate composition , nutrient status and enzymatic activity under mixed forest of chinese fir alniphyllum fortunei and pure stand of chinese fir , the results indicated that , compared to pure stand , the soil structural property was ameliorated , the soil capacity of nutrient supplying and was improved , and the soil enzymatic activity were enhanced 文摘:通过对杉木拟赤杨混交林及杉木纯林土壤团聚体结构、土壤养分状况及酶活性的研究表明,与杉木纯林相比,混交林土壤结构性能得到改善,供肥和保肥能力加强,各种土壤酶活性提高,土壤肥力较好。
On the basis of systematic analysis of policies , technology of conversion of cropland to forest , and the status of rehabilitation ecology , it is discovered that all the existing researches focus on polices and technology of conversion of cropland to forest , but the researches , on relations between conversion of cropland to forest and regional sustainable development , as well as the agricultural structure regulation , are rather rare 在系统的分析、研究国内外与退耕还林相关的政策、技术、恢复生态学等研究现状的基础上,发现现有的研究集中于退耕还林技术和政策的研究,缺乏退耕还林与区域可持续发展关系、与农业产业结构调整的研究。
Lin hsiang - yi points to two similar - looking barrels , then reveals that one is more than twice as expensive as the other . lin explains that juniper and fir have different characters , and what wood is best depends on the intended function . for example , bathtubs use juniper , but fir is good enough for a water barrel 林相林指著两个看起来差不多的桶子,但价格却相差两倍以上,说明杉木与桧木的不同性质,得视桶子的功能来决定最佳材质,比如说,洗澡盆用桧木,留水桶用杉木即可。
