喀斯特石漠化区不同处理方式下滇柏的生长状况——以贵州省陈家寨为例

通过对陈家寨石漠化区综合治理过程中对比、客土、施肥、保水剂、覆盖、保水剂+覆盖6种不同处理方式下柏树林样地的连续观测,对不同处理方式下柏树的生长状况的总体趋势进行了研究。以2年为周期,通过不同时段4次采样,对柏树的高度、基径2个指标的测量。研究结果表明,各种处理方式下柏树的生长状况都得到了明显的改善和提高,其生长程度为保水剂+覆盖保水剂客土覆盖施肥对比。由此可以看出,通过人为的干扰方式,能够有助于植被的生长,有效缓解石漠化的加剧,从而为该区在石漠化综合治理中提供可借鉴的依据。

Different Growth Status of Cypress under Each Treatment in Karst Rocky Desertification Area---A Case Study of Chen Jiazhai,Guizhou Province

This paper makes a continuous observation of cypress forest plots in process of the comprehensive management for Chen Jiazhai rocky desertification areas with six different processing way, such as contrast, soil, fertilizer, water retention agent, covering, water retaining agent + coverage. And then, analysis the growing status of cypress under the different treatments. The height and base diameter of cypress through four sampling in different periods with 2 year cycle were measured. The results showed that cypress growth under the different treatment has been significantly improved, the degree of growth in order to aquasorb and coverage > aquasorb > soil > coverage > fertilizers > contrast. It can be seen that human interference can contribute to the growth of vegetation, alleviate the rock desertification, so as to provide a reference for the comprehensive treatment of rocky desertification.
