Through the analyses of characteristics of gully thalweg and soil erosion in upland and gully land, sediment sources in small watershed, sediment yield relationship between upland and gully and ecological functions of vegetation corridor, it is considered that vegetation corridor combined with land preparation measures may block runoff and sediment from upland and reduce the amount of soil erosion in a watershed by 54. 5 % ~ 77. 0 %
摘要在分析黃土高原地區的溝沿線、溝沿線上下溝間地和溝谷地土壤侵蝕特徵、小流域泥沙來源、坡溝侵蝕產沙關系的基礎上，結合廊道的生態功能和以往的研究結果，認為在溝沿線的上部建立草灌與整地工程措施相結合的植物廊道，來攔蓄阻截溝間地的來水來沙，可使流域的土壤侵蝕量減少54 . 5 % ~ 77 . 0 % 。It was the heavy clay land of blackmoor vale, and a part of the vale to which turnpike - roads had never penetrated
這就是黑荒原谷的粘質土壤地帶，在谷內這一部分，收稅的卡子路一直沒有延伸進來。Soil environmental effects of carex. meyeriana mire in the changbai mountain valley
長白山區溝谷濕地烏拉苔草沼澤土壤環境效應Dynamic change and environmental effects of soil microorganism in marsh soils from carex meyeriana wetlands in changbai mountain
長白山溝谷濕地烏拉苔草沼澤濕地土壤微生物動態及環境效應研究All of theses database was integrated into a land information system, which can be used to land evaluation and land use analysis. the second part is the application of soter land information system in land evaluation, based on water balance model watsat, crop simulation model ps 123 and ales ( automated land evaluation system ). the handan land evaluation model was built in ales based on expert knowledge and farmer s " experiences, it includs three decision trees, namely soil erosion risk, soil water condition and soil fertility
以邯鄲地區1 25萬soter土壤土地數據庫為基礎，探討了土壤參數區域化問題，並利用watsat區域水分平衡模型，研究了邯鄲地區區域水分平衡：大部分地區土壤水分滿足夏玉米生長需求， （ suff ）值為0 . 8 - 1 . 0 ，非常適宜；部分地區如大名地區、邯鄲和永年部分地區、涉縣溝谷坡梁地區土壤水分適宜夏玉米生長， suff值0 . 4 ? 0 . 8 ；不適宜地區， suff值0 . 2 ? 0 . 4 ，主要集中於丘陵山區以及平原古河谷地礫石和粗砂分佈區。The biggest diurnal albedo is 0. 24 and the smallest 0. 11. moreover, the peak occurs on the day that radiation is very strong and the soil surface is dry and the valley appears on the day that rainfall is much more before this day and the soil water content of upper layer is high
就反射率的日際變化而言，最大反射率為0 . 24 ，最小為0 . 11 ，相差一倍以上，其峰值均出現在輻射比較強，地表比較乾燥的日期，而谷底一般是在前期降雨較大，表層土壤濕潤時出現。This dissertation is mainly about regional land resource evaluation and land use analysis based on g1s and soter ( soil and terrain spatial and attribute database ) database. the research content is composed of three parts. the first is medium scale soter database study, in this part, the new landform indexes are studied, which are elevation classification, slope classification and relief index classification
在邯鄲地區1 25萬soter土壤土地數據庫建立方面，主要探討了適用於該比例尺的主地形體指標，提出海拔高度分組指標、坡度分組指標和地勢起伏強度分組指標，並利用上述三個指標組合劃分出邯鄲地區中坡度丘陵（ sh ） 、低坡度山前臺地（ lm ） 、山谷（ lv ） 、中坡度山體（ sm ） 、山前傾斜平原（ lf ）和沖洪積平原（ lp ） 6個主地形體組分。The plants growing on the land surface can be affected by the occurrence and movement of water and salt in the aeration zone. in order to understand the characteristics of occurrence of water and salt in the aeration zone, we installed three tensionmeter systems. which includes 35 ceramic cups, in the soil of ejnqi oasis on the downstream of heihe river in inner mongolia province. the moisture potential distribution in aeration zone was observed, and the samples of water and soil were collected along the heihe river
為了了解綠洲包氣帶水分、鹽份的分佈特徵，我們在黑河下游的內蒙古額濟納旗綠洲安裝了3組35支負壓計，觀測包氣帶中的水土勢，並沿黑河河谷從下游的額濟納旗到中游的張掖採集土樣和水樣，測試土壤的易溶鹽和潛水的化學成分，從包氣帶中水土勢和鹽份兩個方面來研究乾旱地區水分和鹽份在包氣帶中賦存和運移規律。Rocks and soils, as well as mountains, valleys and plains, differ greatly from place to place.
巖石和土壤，以及山、谷和平原，各地差別很大。分享友人
