查询词典 farmland

The results showed as follows:(1) the de-farming index of 479 investigated farm households is 79.21% with per capita area of de-farming slope farmland of 0.205 hm~2,per capita grain yield loss resulted from de-farming slope farmland of 74 kg and per capita allowance of 171 yuan from the government in 2003;(2) the de-farming allowance from the government has a bigger influence on a poor household,and if an allowance from the government would be stopped,the re-exploitation of partly de-farmed slope farmland is possible;(3) in 2003,per capita cash income of 479 investigated farm households is 1 492 yuan,and its sources mainly from floating employment,selling grain and greenstuff,de-farming allowance,selling products of domestic livestock and poultry and dealing dicker etc.;(4) in a few coming years,those employments of stable and higher earning will be firstly selected by farmers,and high expected value agriculture or rural commerce are going to become the leading livelihood of a good few farmers with some fund or skill.

结果表明：被调查农户人均退耕坡地0.205 hm2，退耕指数达79.21%；2003年479农户因退耕导致的粮食减产量人均74 kg，得到政府补贴人均171元；退耕补贴对贫困农户的影响程度较大，停止退耕补贴后存在反垦可能性。2003年被调查农户人均现金收入1492元，主要来源于外出打工、卖粮菜、退耕补贴、卖畜禽产品和做小生意等。未来几年，能获得稳定收入且报酬相对较高的行业是农民谋生的首选，有资金积累或一定技能的农户正在将生计转向高附加值农业或第三产业。

We then follow the trend of farmland pattern evolution and take 2001 as the baseline year to forecast the farmland pattern in 2002 through 2010 using linear extrapolation. The result shows that the clustered rather than scattered farmhouse development type would create more integrated farmland pattern through patch integration and form more regular patch shapes that in turn have better effects on farmland utilization.

The results showed that grassland and farmland were the main land use types of research area with obvious reciprocal transformation. Grassland was mainly transferred to farmland in 1975-1990. Farmland was chiefly converted to grassland, and grassland tended to increase in 1990-2004. The landscape diversity in the study area rose with the contagion index decreasing and fragmentation degree being intensified during 1975-2000. The advantageous patches maintained good connectivity with the increasing patch cohesion index and the decreasing landscape fragmentation during 2000-2004. The change of human interference intensity played an important role on the variation of land use structure. Land use intensity was mainly affected by the changes in population as well as national land use policies. In the following 20 years, the agriculture land area would tend to decrease, the grassland and unused land area would have a slight reduction by contrasting the increasing the forest land area notably.

结果表明，近30 a来，草地和农业用地面积在该研究区占居主导地位，并且它们之间发生着明显的相互转化。1975－1990年，草地主要向农业用地转移，1990－2004年农业用地主要转化为草地，草地面积增加；1975－2000年，研究区景观多样性升高，蔓延度指数下降，破碎化程度加剧；2000－2004年景观内优势斑块具有了很好的连接性，聚集度增大，整体景观格局破碎化程度降低；人为干扰强度的变化对土地利用结构的变化具有重要作用，土地利用强度主要受人口数量以及国家土地利用政策的影响；在未来20 a间农业用地面积会继续减小，草地、未利用土地面积将有小幅度降低，林地面积会显著增加。

Projects to protect the natural forests and wetlands, and to reconvert farmland into forest or pasture have been carried out on the upper reaches of the Yangtze River. In 2002, the goal was to reconvert some 13,000 ha of farmland into forest. The Central Government provided 10 million yuan as subsidy for seedlings, and 15 million kg of grain and two million yuan as allowance for families of farmers and herdsmen whose farmland had been restored to forest.

在长江上游实施天然林保护工程，退耕还林、还草和湿地保护工程2002年共安排退耕还林任务1.3万多公顷，当年中央补助种苗林费1000万元，给退耕还林农牧户补助粮食1500万公斤，生活费200万元。

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。
