裸露土壤
英文
bare soil-
Therdly because of the influence of terrain and geological structure, arenaceous resources of different regions are different in mu us. sands are mainly from riverway in northwest ; from efflorescent cretaceous sandstone on account of higher topography in the middle part of mu us ; and sands resources are intricated in southeast, mainly including riverway sands, sands blown by the wind and embedded sands under so
3 、毛烏素沙地因受地形和地質構造影響，不同區域的砂質來源情況不盡相同，西北部地區主要為河道沙；中部地區地勢較高，為白堊系基巖裸露而風化成沙；東南部地區沙質來源情況復雜，主要有：現代河道砂、風積沙、也有埋藏在現代壤土之下的出露古沙。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。The research results mainly show : ( 1 ) the ecological degradation characteristics of wuxi county include : some soil is thin and barren and its water and fertility conservation abilities are poor, gradual degradation of soil results in decrease of vegetation diversity and the vegetation community structure gradually inclines tc simplicity from complexity. the types of soil and water loss in wuxi county mainly involve surface erosion and gully erosion. according to investigation, surface erosion area occupies 80 % or so or erosion area, in which the slope farmlands surface erosion area accounts for about 70 % of farmland erosion area
研究結果主要包括： （ 1 ）巫溪縣生態退化特徵表現：作為生物生長基質的部分土壤薄而貧瘠，保水保肥能力差，部分地區基巖裸露，土壤的不斷退化導致植物種多樣性減少，植物種群結構逐步由復雜趨向簡單化；縣內水土流失的類型主要包括面蝕和溝蝕兩大類，據調查，面蝕面積占侵蝕總面積的80左右，其中坡耕地面蝕佔耕地侵蝕面積的70左右。Validation of the presented approach is verified through numerical simulations of radar measurements over the bare soil surfaces
本研究以裸露土之土壤?度及其雷達散射系數的數值模擬來驗證此一方法之有效性。According to the meteorologists view, the dust weather has much to do with the scarcity of rain, the dry air and exposed soil with immature plants in the area
據氣象專家說，惡劣天氣是由天旱少雨、空氣乾燥和植被稀少後土壤裸露造成的。Then when you take your tent away, the earth will not be left naked and the rain will not flow down with all the earth. and later we will have mountains no more
而且當帳篷拆掉以後，土壤也不會因為裸露出來而被傾瀉下來的雨水沖刷掉，不然以後我們就沒有山了。M : according to the meteorologists view, the dust weather has much to do with the scarcity of rain, the dry air and exposed soil with immature plants in the area
