In about a century' s time, their livelihood of swidden agriculture has been changing greatly along with the natural and social environment change. Before 1950s, as a minor group frequently move in the subtropical mountainous area characterized by scarce arable land, high forest coverage rate and sparse population, Kemu people has long been engaged in swidden agriculture which was simple, called for no sophisticated production tools and was suitable for frequent movement. At that time, they adapted to the environment change mainly by moving frequently from one place to another, and their livelihood was featured by complete dependence on environment, frequent movement and swiddening without continuous cultivation. From 1950s to early 1970s, their way of adaptation changed into migration within defined territory and shortterm fallow featured by complete dependence on environment, migration within limited area and short fallow. In early 1970s, they leaned from outside to cultivate irrigated fields and plant cash forest and their livelihood was featured by complete dependence on environment and agro-forestry.

近一个世纪以来，随着其所处自然环境和社会环境的变迁，其刀耕火种的生计方式在不断地变化：20世纪50年代以前，作为频繁迁徙于山多地少、森林覆盖率高、人烟稀少的热带、亚热带山区的弱小族群，以开发容易，便于流动作业不需要复杂生产设施的刀耕火种为其传统的生计方式，主要以迁徙的方式对环境变迁进行调适，其刀耕火种生计方式的特征表现为完全依赖型、随意迁徙型、无轮作型；20世纪50年代至70年代，其主要以固定区域内迁徙和短期轮作的方式对环境变迁进行调适，其刀耕火种生计方式的特征表现为完全依赖型、在固定区域迁徙型、短期轮作型刀耕火种；20世纪70年代初，其主要以外文化——开拓水田及人工造林的方式对环境变迁进行调适，其刀耕火种生计方式的特征表现为部分依赖型、粮林轮作型刀耕火种；20世纪80年代以后，其主要以发展橡胶种植业对环境变迁进行调适，其刀耕火种生计方式的特征表现为暂时依赖型刀耕火种。

The results of field trial indicated that the best proportion of pacy was composed of 24.7% parathion and 0.3% cypermethrin. At the rate of 375～562.5 g/km 2, the control effect was over 90% and could last 10～15 days. In 1996 the area of field experiment was 47000 km 2 and the economic benefit was great.

The results show that the formation of the shear band is characterized with both strain localization and the localization of the averaged pure rotation ratio. The shear band starts right at the point where the volume strain changes from shrinkage to expansion. The development of these variables are significantly different within or outside of the shear band. Particularly, the stress-strain softening relationship was observed near or within the shear band, while the hysteretic phenomenon takes place outside the shear band. In addition, both the volumetric and deviatoric strains are larger inside than outside the shear band, with the soil being looser in the shear band.

研究表明：砂土剪切带的形成过程即为试样内部应变局部化过程，也为试样内部平均转动率(averaged pure rotation rate， APR)的局部化；剪切带开始形成点也为试样剪缩、剪胀分界点；剪切带内外各宏微观参数变化规律上存在明显的差异，主要表现为近剪切带位置土体及带内土表现为应变软化现象，而距带中心较远土体应力应变关系曲线出现'回滞圈'现象；带内变形量明显大于带外，且带内较带外松散。
