查询词典 cultivated

Through consolidating the lands rationally and scientifically, the effective areas of cultivated lands can be obviously increased, and the qualities of the lands can be improved. The method can accelerate the land use at the level of intensivism, and realize the dynamic equilibrium of total cultivated land at last. Simultaneously, the method also can relieve the contradictions between people and lands, and improve the conditions of agricultural production and ecological environment. It can ensure the sustainable use of land recourses and make a full satisfaction for the demanding of land recourses on the social and economic development

同时对我国当前农村土地开发整理的模式进行了论证，通过对土地科学合理的整理，不但能增加有效耕地面积，提高土地质量，促进土地集约利用，实现耕地总量动态平衡，同时还可以缓解人地矛盾，改善农业生产条件与生态环境，保证土地资源的持续利用，满足社会经济发展对土地资源的需求。

The results showed that the differences of spatial changes between cultivated land and population in Shaanxi Province are significant. However, the change distribution pattern is basically identical. There is little relative change in southern Shaanxi, while it is volatile in northern Shaanxi and central Shaanxi plain. The cultivated land gravity moves 11. 67 km to northeast during the past 52 years, and the population gravity moves 17.35 km to northeast. The whole trends of them are alike and the distance between two canters of gravity pushes 6.29 km close.

结果显示，陕西省耕地和人口各自空间变化区域差异显著，但变化分布格局大致相同，陕南地区相对变化较小，陕北地区和关中地区中部部分区域相对变化较大。52年来耕地分布重心向东北方向移动11.67 km，人口分布重心向东北方向移动17.35 km，两者整体走势相似，两重心之间的距离推近了6.29 km。

In order to make the quality utilization of cultivated land to move toward the whole nation and the world, to take natural condition of cultivated land as basis, market as guidance, intensive farming and a grand gathering of faming as pattern, bring forth new science and technology, texture adjustment of agriculture as lever, sustainable development as goal must be persist in.

The results show that an internal and mutual transformation of land-use types cause striking changes in soil erosion extent. The transition of cultivated land to woodland and grassland medicates erosion intensity, and the one from forestland to cultivated land and grassland aggravates erosion. In addition, land-use practices, including mainly human activities, have impacts on the content of suspended sediment.

研究表明，本区土地利用类型的内部转化和相互转化引起土壤侵蚀程度的明显变化；耕地向林地、草地的转化使侵蚀强度指数显著降低；林地向耕地、草地转化，均显著增加侵蚀强度指数；耕地、林地、草地的内部转化对土壤侵蚀也有少量影响。
