The Farming-pastoral Zone in North China was separated into 8 Eco-regions according to the known Eco-region. The dissertation analyzed the regional differences of land use changes from three aspects on dynamic degree , land use degree and the change direction (1)On land use dynamic degree, the dynamic degree of the cropland was the highest in North warm temperate deciduous broad-leaved forest and the lowest in temperate forest steppe; forest land's was the highest in alpine meadow and the lowest in warm temperate forest steppe; grassland's was the highest in temperate forest steppe-bunchgrass steppe and the lowest in alpine meadow; other land's was the highest in North warm temperate deciduous broad-leaved forest－the Huang-Huai-hai plain and the lowest in warm temperate bunchgrass steppe.

In modern physics research, the calculus of variations has a broad application of law. As a solid mechanics, structural mechanics and computational mechanics of the theoretical foundation, it has important value in theory and practice on the mechanics; Variation method ruled out the perturbation of the restrictions can be widely used in many state-level and the state function in the calculation in the optical; Calculus of variations can be calculated with the parameters, we can guarantee the reliability of the results, can effectively reduce the workload of calculation, It can be said that the applications of calculus of variations are very broad.

在现代的物理学研究中，变分法有着广泛的应用：在力学上，变分法作为固体力学、结构力学及计算力学的理论基础，在理论上和实践上都有重要的价值；在光学上，变分法排除了微扰法的限制，可以广泛应用于诸多定态能级和态函数的计算中；在量子力学的应用中，具有可算出系统的参数，既可以保证计算结果的可靠性，又能有效地减少计算的工作量等的优点，可以说变分法的应用领域十分广阔。

Result In peanut seedling stage, spraying 900 ml/hm^2 quizalofop-P-ethyl EC on the grass weeds such as Barnyard grass, Green bristlegrass and Goosegrass had 100% control effect, but it had a poor control effect on some broad-leaved weeds. While, spraying 600 and 720 ml/hm^2 quizalofop-p-ethyllactuofen EC had remarkable effects not only on the grass weeds such as B. grass but also on the broad-leaved weeds such as Purslane, Cirsium setosum and Dayflower, with the control effect of more than 80%. Both of the 2 herbicides would not produce some slight contact drug spots on the part of peanut leaves and the drug spots on the leaves could be recovered in 1 to 2 weeks, which couldn't affect the growth and yield of the peanut in middle and late stage. So the 2 herbicides had good selectivity.

结果］在花生苗期喷施900 ml/hm^2精喹禾灵乳油对稗草、狗尾草、牛筋草等禾本科杂草具有100%的防效，但对一些阔叶杂草防效较差，而喷施600和720 ml/hm^2精喹乳氟禾乳油则除了对稗草等禾本科杂草有特效外，还对马齿苋、刺儿菜、鸭跖草等阔叶杂草具有显著的防效，均达80%以上。2种除草剂均对花生叶片局部产生一些轻度的接触性药斑，药斑在12周内可恢复，不影响花生的中后期生长及产量，具有很强的选择性。
