生态幅度

但是有许多水稻-杂草群落生态幅度大，可以分布到全国各地。

But some of the rice-weed communities which have widely ecological amplitude can distribute everywhere in China .

结论塔里木盆地存在着丰富的蜱类群落，且这些群落在该地区整个生态幅度上存在连续的梯度变化。

Conclusions There are abundant tick communities in the area of Tarim Basin , and a gradient change of the communities is continued in the ecological amplitude of this area .

结果表明：L值愈小，B值愈大，物种的资源利用能力愈强，生态幅度愈大，对某一资源的依赖性愈小；反之亦然。

The results show that the little lis , the bigger B is , the stronger the capability of resource using ;

在这种新模式的构建中，整个团队及其中成员的生态发展幅度明显加大，其自身生存、对外交流的活力也明显提高，显示出旺盛的生命力。

In the Construction of this new model , the whole team and its members significantly increase the ecological amplitude , and its own survival , ability of interaction are also markedly improved , and showing great vitality .

这种差异可能与物种的生态适应性和生态幅度有关。

The differences may be related to ecological adaptability and ecological range of the species .

生产性生态足迹的上升幅度远远大于生态承载力的下降幅度，生态赤字越来越大，生态环境承受着巨大的压力。

The ecological footprint increased much faster than the ecological capacity . As a result , the total ecological deficit became more and more larger and the eco-environment took serious pressure . 3 .

将原本为负的生态效益扭亏为盈，湿地生态效益大幅度改善，对土地的可持续利用具有积极作用。

A significant improvement in ecological benefits of wetlands has a positive effect on the sustainable use of land .

总的来看，群落优势种群生态位的测定表明：种群生态位宽度越大，物种对生态因子的适应幅度就越大，在群落内的分布幅度也就越大，对各种资源的利用也越强。

As a whole , the dominant population determined niche : niche breadth , the greater the population , species adapt to ecological factors on the greater range in the distribution of communities within the greater rate of utilization of various resources stronger .
