  1. Therefore, it is the urgent need of land exploiture and environment repair that how to investigate the current situation of soil losses accurately, quickly and dynamically, how to predict & inspect soil losses, and provide scientific base for the repair of soil erosion and implement of soil and water conservation planning. otherwise, the survey method of soil losses is lagger in yunnan

    如何準確、快速、動態地查清水土流失現狀，進行水土流失預報和動態監測，為水土流失治理和水保規劃實施提供科學依據，是土地開發與環境整治的迫切需要，而雲南省在水土流失調查方法方面恰恰處于相對落後狀態。
  2. It divides the main vegetation of the headwater region of huangpu river into 4 categories based on field survey and observation and methods of factor analysis and systematic cluster analysis and according to the degree of soil and water conservation function : deciduous trees and shrubs are category 1 which shows very strong soil and water conservation function ; tea plantation, grasslands and pine trees are category 2 which has stronger function ; the category 3 is moso bamboos and broadleaved evergreen trees which have stronger permeability and erodibility, but the permeable performance is not outstanding, the capacity of soil moisture storage common and soil and water conservation function moderate and ; the category 4 is uncovered land where the soil and water conservation function is very weak and its permeability, erodibility, erosive resistance and soil moisture storage capacity are all notably smaller than that of the other lands

    摘要在野外調查、實測的基礎上，採用因子分析、系統聚類分析的方法，根據土壤層水土保持功能的強弱，將黃浦江源區主要植被類型分為4類：落闊林、灌木林為第一類，表現出很強的水土保持功能；茶園、草地、松林為第二類，土壤水土保持功能較強；毛竹林、常綠闊葉林表現出較強的抗蝕性和抗沖性，但滲透性能並不突出，土壤貯水能力也一般，水土保持功能中等，為第三類；裸露地水土保持性能很差，單獨作為第四類，其滲透性、抗蝕性、抗沖性、土壤水庫容都顯著小於其他各樣地。
  3. It decides the protective objectives for different ecological reserve area based on the study of channel wetlands and survey and analysis of top - grade species ( fishes ) of the yellow river : from the point of the basin, the main ecological protective objectives of the tipper stream are vegetation and forest for conservation of water supply ; soil and water conservation is the main in the middle reaches for vegetation protection and rehabilitation and ; the lower reaches takes types of wetlands protection and wetlands area maintenance as the main, protecting biodiversity and important birds resources

    在黃河河道濕地研究和黃河水體內頂級物種（魚類）的調查分析基礎上，確定了黃河不同類型生態保護區的生態保護目標：從流域角度而言，黃河上游的主要生態保護目標是植被和水源涵養林；中游應以水土保持為主，主要是恢復和保護植被；下游以保護濕地類型和維持濕地面積為重點，保護生物多樣性和重要鳥類資源。
  4. In the first place, the study processed data of remote sensing and non - remote sensing to be digital, vector, raster and imagery geocode, established geographic database of soil erosion, and calculated elements " pixel maps of soil erosion. secondly, by using model builder of arcview to establish dynamic survey model of soil losses in longchuan river drainage basin. at last, to obtain maps of status & the forecast maps for soil conservation

    首先通過遙感與非遙感資料的數字化、矢柵化及圖形圖像地理配準，建立了水土流失地理數據庫，並運算出水土流失各因子像元圖；在此基礎上，憑借arcview子模塊modelbuilder的支撐，建立龍川江流域水土流失動態監測模型；最後運行該模型獲取水土流失現狀圖和防治預報圖等結果圖件，完成了研究區1998 、 1999年水土流失定量遙感監測任務。
  5. The comprehensive survey domestic and foreign these research, they often all are concentrate with some on the one hand, for instance countryside land property right joint stock system research, some focusing in countryside land property right system and countryside marketability question research, also some research countryside land property right between system and conservation of water and soil relations and so on

    綜觀國內外的這些研究，他們往往都是專注與某一方面，比如農地產權股份制研究，有的著眼于農地產權制度與農村市場化問題的研究、還有的研究農地產權制度與水土保持之間的關系等等。
  6. At least 1 full - time engineer who holds a civil, hydraulic, survey, environmental, structural, earth or water and soil conservation engineer certificate or architect certificate, has studied courses related to civil engineering and construction for some credit hours before getting the engineer certificate through exam, and has worked in civil engineering and construction for over 2 years

    一置領有土木、水利、測量、環工、結構、大地或水土保持工程科技師證書或建築師證書，並於考試取得技師證書前修習土木建築相關課程一定學分以上，具二年以上土木建築工程經驗之專任工程人員一人以上。
