現(xiàn)有的大量研究表明，酸雨對土壤生態(tài)系統(tǒng)的功能特性，包括土壤的鹽基離子以及重金屬與微量元素的淋溶、土壤營養(yǎng)、土壤酸化、土壤微生物數(shù)量及其活性、土壤緩沖性能、土壤對酸雨的敏感性、土壤結(jié)構(gòu)、土壤礦物風化等方面均會產(chǎn)生一定的影響。 - It's difficult to find soil acidification in a sentence. 用soil acidification造句挺難的
- This article , with the help of gis , first uses geostatistics to study temporal and spatial changing of soil fertility factors , such as oganic matter total n total p , total k available k available p ph and cec , in wujin city in nearly 20 years , and draws these conclusions : soil acidification of large area exists in the city , the content of n is generally lower but it tends to rise , the content of p and k is lower and it ' s still lowering , the content of organic matter is medium but it tends to add , cec ' s quality grade is higher but its content is lowering
土壤肥力質(zhì)量時空演變對于農(nóng)業(yè)生態(tài)與社會、經(jīng)濟的持續(xù)發(fā)展意義重大，而gis在土壤肥力質(zhì)量評判中發(fā)揮日益重要的作用。本文首先基于gis支持下，運用地統(tǒng)計學，研究了武進市近20年全n 、全p 、全k 、有效p 、有效k 、 ph 、 cec和有機質(zhì)等土壤肥力要素的時空分異狀況，得出：存在大面積土壤酸化現(xiàn)象、 n素含量總體較差但趨于提高、 p素和k素含量較低且繼續(xù)降低、有機質(zhì)含量中等但有增加趨勢、 cec質(zhì)量等級較高但含量趨下降。 - Agricultural intensification plays an important role in stabilizing the food production in china , while bringing about an increasing negative impact on the soil and eco - environment as a result of the long - term highly - intensive land use and agricultural chemical overuse , thus leading to degradation of soil physical , chemical and biological properties , which are demonstrated as soil nutrient imbalance , soil acidification , pollutant accumulation , and biodiversity deterioration and posing serious stress and threat to the ecosystem per se and the environment
摘要集約化農(nóng)業(yè)對保障我國糧食安全發(fā)揮了巨大的作用，但其長期的土地高強度利用和農(nóng)用化學品過量投入的負面影響也日益顯現(xiàn)，導(dǎo)致的以土壤養(yǎng)分失衡、土壤酸化、有害物質(zhì)積累、生物多樣性衰退等為主要表現(xiàn)形式的土壤物理、化學和生物學退化，給生態(tài)系統(tǒng)本身與環(huán)境都帶來了巨大壓力和嚴重威脅。 - Agricultural intensification plays an important role in stabilizing the food production in china , while bringing about an increasing negative impact on the soil and eco - environment as a result of the long - term highly - intensive land use and agricultural chemical overuse , thus leading to degradation of soil physical , chemical and biological properties , which are demonstrated as soil nutrient imbalance , soil acidification , pollutant accumulation , and biodiversity deterioration and posing serious stress and threat to the ecosystem per se and the environment
