- Purification of surface water nitrogen and phosphorus pollutants by zhalong riparian wetland
扎龙河滨湿地对地表径流氮磷污染物的净化作用 - Results showed that available k and ( no3 ) ^ ( - 1 ) content were higher in surface runoff in slope cropland and intercrop land between crop and forestry than those in fallow land , intercrop land between forest and grass and afforestation land
研究结果表明: ( 1 )坡耕地及农林间作下地表径流中的有效钾和硝态氮含量高于撂荒荒坡、林草间作和造林林地。 - We explored the changing trends in agricultural water demands , the changing trends and variability in soil moisture associated with both drought and increased surface runoff in chinese croplands during the last half - century ( 1946 - 95 ) as well as the projected future years ( 2031 - 65 ) , and their impacts on agricultural production
摘要作者进行一项农业用水需求变化趋势之研究,收集包括中国大陆农耕地在干旱及高地表径流量之土壤水分变化趋势与变异幅度和对农业生产冲击,涵盖过去1946 - 1995年之五十年资料及未来2031 - 2065年之预测值。 - Absolute amounts of soil erosion is not large for the falling gradient in black soil region , but the nutrient is high in erosion soil , the nutrient of erosion soil and runoff is high , which leads to soil fertility degeneration , while n and p nutrient pour into water with surface runoff , it leads to water nutrient enrichment and pollution , and becomes one of confined factors of water nutrient enrichment
吉林农业大学硕士学位论文黑土地表径流氮磷养分特征及其与肥力退化的关系由于黑土耕作区坡度平缓,土壤侵蚀的绝对量并不很大,但由于土壤中携带的养分高,养分流失的较多,流失的养分将引起肥力的退化,而且氮磷等养分随地表径流流出汇入各种水体,引起水体富营养化和污染,成为水体富营养化的限制因子。 - The paper studies on two different vegetation type areas in jingyun mountain in chongqing city , which are broadleaved forests ( gordinya svchuanensvs ) and bamboo ( phyllostachys edulis ) forests . by contrasting the surface runoff and underground runoff in these two areas , the results showed that , with the same precipitation , the gross amount of runoff in bamboo forests was larger than that in broadleaved forests and the runoff in bamboo forests appeared before that in broadleaved forests . the amount of underground runoff was larger than that of surface runoff in the two areas , the process of surface runoff was in accordance with that of underground runoff
该文以重庆市缙云山的两个不同植被类型常绿阔叶林(四川大头茶)和楠竹林小区为研究对象,对小区中典型降雨后的地表径流、地下径流的实测资料进行对比分析.结果发现在相同降雨条件下,楠竹林的地表径流量与地下径流量明显要比常绿阔叶林的大,楠竹林地表径流和地下径流出现的时间也比常绿阔叶林早;两种植被的地表径流与地下径流过程具有一定的相似性,地下径流量都比地表径流量大
