代写论文:城市化及其对农业用地的影响

保护土壤的方法:
我)使用的做法没有到农业这将有助于在保持土壤固定,防止它被暴露于风和水。
2)练习阳台农业在这个土地用于减缓水流的梯田。它减缓水流的速度,从而防止冲走土壤农田。
iii)等高种植的作物种植在上下两边的山为简单的水流创建路径。平行等高种植作物种植土地,由于水流缓慢,防止水土流失(防腐,1967)。
iv)的减少不透水表面的使用允许自由流动的水和土壤侵蚀的结果从流银行和河岸。铺路石应该用于天井这将有助于在水中吸收到土壤里去的。
v)种植一个雨水花园可以帮助使用收集到的降水不透水表面的水,可以进一步用于种植湿地植物。

(六)雨桶可用于收集雨水,它可以进一步用于农业土地保护土壤。
七)种植树木和灌木风打破减缓压力的风力侵蚀表层土壤形成一个开放的地面。
八世)恢复湿地作为吸水的海绵,从而阻止了表层土壤侵蚀快速流动的雨水。
ix)种植缓冲条树,草和灌木在河有助于保持银行的银行完整的洪水时期(艾伦,2004)。

Ways to conserve soil:
i)                    Using the practice of no till farming this will help in keeping the soil anchored and will prevent it from being exposed to wind and water.
ii)                  Practicing Terrace farming as in this the land is used to slow down the water flow because of the terraces. It slows down the speed of water flow and thus prevents washing away of soil from farmlands.
iii)                In contour farming the crops are planted in up and down sides of the hills that create pathways for the easy flow of water. In contour farming crops are planted parallel to the land that prevents soil erosion due to slow flow of water (Wolman, 1967).
iv)                The reduced use of impervious surfaces which allows free flow of water and results in the erosion of soil from the stream banks and lakeshores. Paving stones should be used in patios which will help in water absorption down into the soil.

v)                  Planting a rain garden can help in using the collected precipitation water from the impervious surfaces that can further be used in growing wetland plants.
vi)                A rain barrel can be used to collect rain water and it can be further used in agricultural lands for conserving soil.
vii)              Planting trees and shrubs as wind breaks to slow down the pressure of wind which can erode the top soil to form an open ground.
viii)            Restoring wetlands which act as sponges for absorbing water and thus prevents the erosion of top soil speedy flow of rain water. 
ix)                By planting buffer strips of trees, grasses and shrubs  at the banks of river helps in keeping the banks intact at flood times (Allan, 2004).
