侗族文化调控下的草地生态系统

Grassland Ecosystems Rnder the Control of Dong Culture

通过调查,发现侗族社区的草地生态系统大致可以分为如下三种类型:一是森林与稻田、鱼塘之间的过渡带草地;二是分水岭山脊地带的疏树草地;三是连片森林之中呈带状形分布的防火隔离带草地。这三种类型的基本构成和服务功能在侗族文化的调控下打上了鲜明的人文烙印,并且因地制宜,使不同类型的草地在侗族居民的生产和生活中发挥相应的服务功能。

Through field work, this research finds that the grassland ecosystem of Dong community can be divided into three types： first, the transitional meadows of forests, rice paddies, and ponds; second, the sparse tree and meadow of watershed areas of mountain ridge ; third, firebreak grass with strip-shaped distribution in contiguous the forest. Under the control of the Dong culture, these three types of basic components and services have marked distinctive humanities mark; also suited to local conditions, so that different types of grass in the production and life of Dong residents, play corresponding service function.
