For Southwestern Margin of Aqikekule Lake ophiolite, their field geological, petrological, minerological, petrochemical and geochemical characteristics show that:① it outcropped as tectonic slices along the near west-to-east strike Kunzhong fault and is composed of metamorphic perodotties, cumulates and volcanic rocks, in which, chromites are distributed in the upper part of metamorphic peridotites as pods, or in the lower part of cumulates as near-strata;② metamorphic peridotites include serpentinites, chromite-bearing serpentinites, chlorite-epidote schists and chromitites, of which, chromitites have nodular and orbicular structure, and cumulates include pyroxenits, serpentinites, chromite-bearing serpentinites, chromites and metamorphically mafic rocks and only basalts are seen in volcanic rocks;③ Cr# of chromites suggest that they formed in the SSZ and Al〓O〓 and TiO〓 of metamorphic peridotites also suggest SSZ environment;④ metamorphic peridotites have V type and enriched LREE patterns, cumulates have from strongly depleted LREE, flat REE to enriched LREE patterns with universally striking positive Eu anomalies and basalts show flat REE or slight enriched LREE patterns with no Eu anomalies;⑤ trace element and Sm-Nd isotope characteristics of metamorphic peridotites imply their strikingly heterogeneous mantle character ε〓(t+4.39～+26.20 and later Nb, Ta fertilization;⑥ trace element characteristics of basalts and their tectonic diagrams show they probably formed in the rifted island arc or back-arc basin environment.

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。
