In general, it seems that the field margin and woodland were much fitter for carabid living than cropland; and it was beneficial to protect and establish such habitat for the biodiversity in agro-ecosystem.3 Because of the long-term intensively agricultural land using and rapid urbanization, the vegetation in the Dongbeiwang village was extremely homogeneous.

不同的生境类型下步甲群落的个体数量差异很大，农田生境中步甲群落个体数量都较低，林地和农田边界地带较高；不同土地利用类型下，步甲群落的物种数量也有显著差异，农田边界处步甲群落的物种数量最多，其次为林地和与边界相邻的农田，而农田中出现的物种数量最少。

According to the result of artificial rainfall, the character and factors affectedby soil, rainfall, chemicals, slope length, slope gradient and field mangment practices, for rainfall, runoff,infiltration, soil erosion and soil chemicals, such as NO_3~-, NH_4~+, PO_4~(3-), K~+ and Br~-, are investigated. Thedeterminate methods, influence factors and practical application of the mixing zone depth are also researched.The results can enrich the dynamics of soil, water and nutrient transport, evaluate the soil water and fertilizerefficiency, and theoretically benefit the research of agricultural NSP on loess hill slope. 1. According to the surface transport experiments of soil chemicals under the non-satuation soil and watererosion condiction, for adsorbed PO_4~(3-) and K~+, the time of sheet erosion and rill erosion initiation is coincidentthat of chemicals content in surface runoff climbs, and then their abundant export by surface runoff is urged.

本文以黄土坡地为研究对象，通过模拟降雨试验，研究土壤因素、降雨因素、化学物质理化性质、坡长坡度因素和农田管理措施等对坡地降雨—产流—入渗—土壤侵蚀—农田NO_3~-、NH_4~+、PO_4~(3-)、K~+和Br~-地表迁移的影响，研究非饱和土壤和水蚀条件下混合层深度的确定、影响因素和模拟，探讨其在黄土坡地的实际应用，为丰富坡地水分养分迁移动力学、提高旱地土壤水分养分利用率和深化农田非点源污染研究提供理论依据。

By analyzing soil quality of 4 kinds of land use types in Kalamay agriculture development area according to principal component analysis, we draw the conclusions: nature shrub tree land is affected little by mankind, a great deal of organic matter return to soil every year, and root system can improve soil physical quality, can absorb salt from soil, so the soil quality of nature shrub tree land is the best; the soil quality of farmland is better than the soil quality of manpower Tamarix Bulrush land, which may be reasoned that man make for soil quality by irrigation to exclude salt and fertilizing organic muck in the earlier oasis digging up period. Soil physical qualities of tree land get harden and worsen for flooding irrigation, furthermore climate in Kalamay is dry and rainless , the other irrigation is very long time after the former one, so soil get harden severity and result soil physical quality get worse and worse.

利用主成分分析法分析新疆克拉玛依农业开发区四种土地利用方式下的土壤质量，得出：天然灌木林地，受人为影响较小，每年有大量有机物质返还土壤，且天然灌木的根系可以很好的改良土壤的物理性质，同时所选天然灌木林灌木多是耐盐碱并且本身又具有吸收积累来自土壤的盐分，土壤质量最好；农田受到的人为影响最大，但农田综合得分却好于人工柽柳芦苇地综合得分，这可能是由于在开垦初期的绿洲农田，受到了人们灌水压盐及增施各种有机无机肥料等有利于土壤质量提高的措施所致；乔木林地，由于人们用大水漫灌的方式灌溉，致使林地土壤变得板结，土壤物理性质下降，加上克拉玛依地区气候干燥少雨，一次灌溉后较长时间后才有下一次灌溉，致使土壤理化性质恶化，土壤质量不高。

Due to food pressure, grain product in the western Jilin Province will be enhanced in the near future. Farmland areas in the area will be decreased slowly in the near future, but with the technique development of irrigation establishment, paddy areas and utilization amount of fertilizer and pesticides will be increased rapidly. So, the NPS pollution from farmland will be more serious. The main lakes in the areas such as Moon Lake and Qagan Lake have been polluted by N and P, and the content of salt in the Nenjiang River has been increasing since last 30 years. All of these show that the negative effects of NPS pollution in the area have been serious and should not be neglected by the scientific research and corresponding government management. To deal with the contradiction of agriculture development and water pollution, the trend of increasing paddy area and using amount of fertilizer, pesticide and herbcide in the western Jilin Province should be controlled. Also, the drainage of return flow from paddy should be controlled and return flow should be disposed with ecotechniques by use of the large areas of lakes and mires in the area. Through these measures, the quality of surface water could be protected and the degeneration of ecoenvironment in the area could be contained.

我国由于粮食压力，未来吉林西部的粮食生产还将进一步加强，随着种植业结构的调整，垦殖率会略有下降，但随灌溉设施的建设与完善，水田面积将进一步扩大，化肥、农药的用量还将快速增加，农业活动引起的非点源污染将更加突出，而研究区的主要湖泊月亮湖、查干湖目前已达中等富营氧化水平，嫩江水质的咸化趋势明显，因此农田非点源污染物的流失及其内流区外流化面积的增加对地表水体富营养化、咸化的作用愈来愈明显，农田非点源对地表水水质的影响已不容忽视，应引起社会的关注，为协调农业发展与水污染这一矛盾，吉林西部应遏制化肥、农药施用量增长过快和水田过度开发的势头，控制洗盐回归水的排放量，利用区内广泛分布的大量泡沼对农田径流和回归水进行生态处理，既保护了地表水的水质，又有利于生态环境的改善。

The average soil moisture content in grassland was about 1 gg^(-1) higher than that in farmland, which was mainly caused by the decreased capillary moisture capacity of farmland.

其中农田－草地复合功能区的土壤含水量变化剧烈，而草地功能区与农田功能区内土壤水分基本呈线性分布；草地生态系统土壤平均含水量比农田高约1 gg^(-1)，这主要是由于草地开垦为农田后风蚀等作用而引起的土壤毛管持水力下降所致。

Meanwhile, the paper also quantitatively studied the response mode of the soil moisture, crop, trees and grass under climate change conditions with the statistical and numerical models.

本研究选择黄淮海流域、新疆、小兴安岭和内蒙古锡林浩特分别作为农田、森林、草原典型生态研究区，利用较长时间序列的气候资料、遥感数据及其他辅助资料，运用趋势、相关、EOF、突变检验、小波分析及数值模拟等多种方法，在分析研究不同生态研究区气候变化区域特征的基础上，较为系统全面地开展了我国北方典型生态区气候变化对农田生态、森林生态和草原生态典型和敏感生态环境指标的影响研究，包括气候变化对农田土壤水分、农作物发育期和产量的影响；气候变化木本植物和鸟类物候的影响；气候变化对植被NDVI、林木生产力和森林生态环境质量的影响；气候变化对草原土壤水分和牧草产量的影响，同时，通过统计模型和数值模型定量研究了气候变化背景下的土壤水分、作物、林木和牧草响应模式。

Result showed that, with the controlled facility, the water storage is about 19×10^3 m^3/km of in the main drainage canal, the groundwater table in farmland is raise about 0.3 to 0.5 m and the crop water use is increased about 50 to 80 mm comparing with the non controlled main drainage canal.

结果表明，单位长度大沟年调蓄水量为1.9×10^4立方公尺/km左右，其影响范围内的农田地下水位较无控制大沟平均抬高约0.3~0.5 m，每年可增加作物对地下水的直接利用量50~80 mm，区域年农田水资源调控总量110 mm左右，约占当地年均降雨量的13%；只要控制合理、管理得当，不会因此而影响排水系统对农田涝渍的有效控制或降低原有排水工程的除涝降渍标准。

July was the critical period for nitrogen and phosphorus losses. FR over 20° should be fallowed.

与不同坡度农田流失泥沙量的顺序相同。20°是农田氮素和磷素流失的临界坡度。20°以上的农田应该退耕。7月份是农田氮素和磷素流失的敏感期。

The observation period was divided into three sub-seasons according the phenology of waterbirds that wintering at the lake, namely: early winter , mid winter , and late winter . Ruddy Shelducks did not evenly distribute in the five habitat types during winter.

即使是在越冬中期，在农田中取食的赤麻鸭对整个农田生境的利用强度也并非一致；它们偏好于在潮湿的农田（灌溉不久或者是正在灌溉的农田）中取食或者是活动，而尽量避免在干燥的农田（近期内没有被灌溉的农田）中取食或活动。

Considering many biophysics processes such as the atmosphere,hydrology,plant leaf N content et al.a multiple layer,two-leaf canopy model for predicting of mass transportation and energy exchange between plant canopies and the atmosphere has developed after dividing the canopy height into three layers,and the sunlit and shaded leaf area index was computed respectively at different layers through introducing a foliage clumping index,it is important to distinguish the spatial light distribution and so leaf photsynthesis.

多层—双叶模型对冠层上方碳通量的模拟：综合考虑农田水、热因子及叶片氮含量的非线性垂直分布对碳、水循环的影响，将农田按植株高度分为上、中、下三层，并通过叶片集聚指数计算阴、阳叶面积以区分叶片的空间分布受光状态，建立了均匀农田与大气间物质输送和能量交换的多层—双叶模型，对农田冠层上方基于光合—呼吸的碳循环过程进行了模拟应用研究。
