The government is helping farmers change their traditional cultivation habits of letting land lie idle after harvest — a centuries-old practice known as "white fallow," which is detrimental to water and soil conservation.

政府帮助农民改变千百年来传统的撂荒式的&白色休耕&等不利于保持水土的耕种习惯，实行粮草轮作等生物手段，提高土壤的肥力和水分涵养能力。

Air, water and soil pollution is brought about with the development of animal husbandry in our country, but due to various nutrition components in feces of livestock and poultry, the excrement can be comprehensive utilized. The livestock feces can be used as fertilizer via composting, as feed via ensiling, dehydration drying or biological treatment; it also can be used to produce marsh gas by anaerobic fermentation.

我国的养殖业迅速发展的同时也对空气、水体、土壤等环境造成污染，但粪便中的各种营养成分决定其可以进行综合利用，包括通过堆肥生产肥料，通过青贮、脱水干燥、生物处理等手段生产饲料，进行厌氧发酵生产沼气等。

介绍了土壤动物研究方法的改进、群落的生态特征、生物指示的作用、微量气体代谢的调控以及简要讨论了将来的发展趋势。

The forages play an important role in animal husbandry production, biologicaldiversity conservation, environment protection, soil improving and so on.

牧草在畜牧业发展、生物多样性保护、环境保持和土壤改良等多方面都具有重要作用。

This paper based on Precision Agriculture development of China, and focused on several key problems for developing Precision Agriculture, especially field spatial information distribution processing method. The trail farm is located in Shunyi, Beijing. The area is 11 hectors. We sampled the soil, and got soil spatial distribute data , crop growing status distribute data (such as crop population, crop height, plant dry weight), yield distribute data (such as yield per mu, ears per mu, seeds number per ear, weight of thousand grain, plant yield).

本文在探索我国精细农业发展道路的基础上，以当前开展精细农业实践急需解决的关键问题之一—农田空间分布信息处理方法研究作为切入点，通过对北京顺义&三高&农业示范区一块面积约11公顷的农田进行了定点采样试验，得到土壤空间分布信息、苗情分布信息（株数、株高、地上干物重等）、产量分布信息（亩产量、亩穗数、穗粒数、千粒重、生物产量等）。
