This indicated that besides the aggravation of salinity , the ratio of agricultural landscape was increased and the ratio of pastoral landscape was decreased 这说明在以长岭县为代表的东北农牧交错带农业比重上升，牧业比重下降，土地盐碱化加重。
But if the temperature and precipitation increase at same time , the transfer of interlock area of farming - pastoral region will decrease , or keep unchanging 而在温度升高、同时降水增加的气候情景下，农牧交错带的移动变缓，甚至不变，视降水的情况而定。
The precipitation is the key factor to determine the boundary and climatic potential productivity of interlock area of farming - pastoral region in northern china 降水是决定农牧交错带位置及其气候生产力的关键因素，但未来干热的气候趋势有可能使该地区的环境状况变得更为严峻。
From climate index , ecotone between agriculture and animal husbandry aridity ranges from 1 . 0 to 2 . 0 , more year average precipitation in ecotone between agriculture and animal husbandry ranges from 250mm to 450mm 在气候指标上，与干燥度为1 . 0 2 . 0范围，多年的平均降水量范围为250 450mm大体一致。 2整个农牧交错带的土地利用特点。
The results indicate that land use options for farming and grazing households in fgtz are the integrated results by many factors such as ecological vulnerability , poverty , tremendous changes of communities and culture 研究发现，农牧交错带的农牧户土地利用选择是生态脆弱、经济能力低下、社会文化变迁巨大等多种因素综合作用的结果。
Suburb was the transition zone between cities and countryside . with the development of economy and urbanization , a new special interspace generated in this zone , which was the urban - rural ecotone 城市郊区是城乡间的过渡地带，随着我国经济的迅速发展和城市化水平的不断加快，在城市建成区和农村之间出现一种新的地域空间? ?城乡交错带。
Abstract : the variation and its driven forces of land use patterns in two pilot regions in the southeastern and southern inner mongolia were discussed . the relation between geomorphic evolution and soil erosion was also addressed 文摘:主要讨论了中国北方农牧交错带中内蒙古东南和中南两个典型地区土地利用的演变过程以及影响因素，并探讨了地貌演化与土壤侵蚀之关系。
For the limited soil resources , we should improve the fertility by the way of reclaiming the lands with high fertility , green manure or burning the grass on waste land , reclaiming sandy lands , and increasing applications of fertilizers and manures ( 4 )农牧交错带土壤瘠薄，农牧民便采取开垦土壤肥力高的土地、沤肥或烧荒、倒沙种田、增旋肥料等措施提高耕地的肥力。
The result showed that in the future climate change scenarios ( temperature increasing and precipitation unchanging ) , the interlock area of farming - pastoral region will shift from the northwest to southeast , and the climate potential productivity will decrease 研究结果表明，在降水不变，温度升高的情况下，现有的农牧交错带将东南移，范围扩大；同时气候生产力可能下降。
Based on field review and data collection , we study the land production potentiality and land carrying capacity in the zone . the main conclusions are as follows . 1 the research estimates the cropland production potentiality by step correct method 本项目在野外考察和资料收集的基础上，对陕北农牧交错带土地生产潜力及人口承载量进行了系统的分析研究，得到以下主要结论和成果： 1采用逐步订正法估算作物生产潜力。
