迁徙

Recently, with the development of market economy and the construction of political democracy, the issue of human rights has been increasingly concerned, among which the freedom of migration has become one of the hottest one in law studies, politics, sociology and demology.

这其中，迁徙自由、迁徙自由权已经成为法学、政治学、社会学和人口学等学科共同的热点话题。

For if a certain type of government is established, or a certain movement of peoples takes place in consequence of certain geographical, ethnographical, or economic conditions, the free will of those persons who are described to us as setting up that type of government or leading that movement cannot be regarded as the cause.

因为，假若由于某种地理条件、人种或经济条件而建立某种管理形式，或发动某一民族迁徙，那么，在我们看来那些认为建立管理形式或发动民族迁徙的人的自由意志就不能被视为原因。

Accordingly, conversion of a population from migratory to nonmigratory can occur by selection with a transition through partial migration.

因此 ，通过选择作用，一个迁徙型种群可以通过部分迁徙型转变为非迁徙型。

There is evidence indicating the existence of an innate migratory drive as well as genetic control of the onset, duration and end of the migration period, the amount of migratory activity, a genetically prescribed parameter that determines the distance over which the bird flies, the migration directions and physiological parameters, in particular fat deposition during the migratory period, but also those determining which individuals will migrate and which will not in forms that are obligatorily partial migrants.

有证据表明，存在某种先天的迁徙动因并涉及以下几方面的遗传调控：(1)迁徙过程的起始、持续以及结束；(2 )迁徙活动量，即决定鸟类飞行距离的遗传参数；(3)迁徙方向；(4)生理参数，特别是迁徙期间的脂肪贮存，以及对于那些部分个体迁徙的鸟种而言，决定个体迁徙与否的生理参数。

From the Arctic to the Cape - the Wings Over Wetlands African-Eurasian GEF Flyways Project is the largest international wetland and waterbird conservation initiative ever to take place in the African-Eurasian region. This 12 million dollar project aims to conserve the critical areas needed by these migratory birds across Africa, Europe, the Middle East, Central Asia, Greenland and the Canadian Archipelago. Through its unique flyway-scale conservation approach, Wings Over Wetlands will not only enhance international conservation efforts to improve the conditions and management of waterbirds and key wetland sites in Africa and Eurasia, it will also create a new web-based information portal that will be an improved source of reliable information on migratory flight paths across the continents.

从北冰洋到南非海角，&飞跃湿地的翅膀&非洲－亚欧大陆GEF迁徙水鸟项目是目前最大的一个国际性湿地和水鸟保护项目，这个项目投资1200万美元，目标是保护迁徙水鸟需要的关键性地区，这些地区囊括了非洲，欧洲，中东，中亚，格陵兰岛以及加拿大群岛，通过这个独一无二水鸟迁徙路线保护项目，WOW将不仅加强提高湿地环境和管理以及在欧洲，非洲关键性湿地的国际性保护，并将建立一个新的信息网络，成为经过这些地区的迁徙鸟类可靠的信息的最新资料库。

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。
