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 groundwater in well-irrigated area, Guangrao county is very important to the agriculture production and their people living.

中文摘要：广饶县井灌区地下水是当地农业生产和人民生活的重要水源。

DI is the most ideal irrigation indicator as it is very much influenced by soil water potential and less affected by meteorological factors. DI value of zero is probably the best irrigation threshold. MDS is strongly affected by meteorological factors and requires reference MDS under well-irrigated conditions. RT on the other hand is not significantly related with soil water potential. Therefore neither of these variables is suitable as irrigation index.

DI 受土壤水势影响产生变化的趋势明显并受气象因子影响较小，是最理想的灌溉控制指标，可将 DI =0作为灌溉控制临界值； MDS 受气象因子影响强烈，变异性较大，且需要充分灌溉条件下的 DI 作为参考， RT 与土壤水势的相关性不高，因此均不适合单独作为灌溉控制指标。
