| 对贵州省北盘江中游花江峡谷段喀斯特高原峡谷中-强度石漠化治理示范区 15 个样地 2012
年的小气候特征进行监测，运用空间代替时间方法分析石漠化恢复过程中环境因子的变化
。结果表明：不同等级石漠化各小气候因子及土壤水热状况均有不同程度差异，小气候质
量最好的是无石漠化环境；随着石漠化程度加深，多数环境因子质量并非直线下降，而是
出现一个先退化后改善的过程；潜在、轻度石漠化受人为干扰最多，小气候质量不高且不
同季节表现紊乱；部分强、中度石漠化环境因多年的石漠化综合治理及较少的人为干扰小
气候效应开始凸显，整体生境朝着良性有序方向发展。 |

| Microclimate was monitored in 2012 by 15 sample plots with different rocky desertification degrees in the
Huajiang Gorge area, which is a Karst plateau gorge moderate-strong rocky desertification area located in middle stream of
Beipan river. Using the method of space instead of time, this paper analysed the environment factor changes in the process
of rocky desertification. The results showed that microclimate factors and soil water content varied in different rocky
desertification degrees, and microclimate quality of N displayed the best. With the increase of rocky desertification degree,most environmental factors showed a process of improvement after degradation rather than lining decrease. Microclimate quality of L and SL displayed not very well and disordered in seasons due to frequent human disturbance. Some
microclimate effects in ST and M started rehabilitation and whole habitat became healthy and orderly development resulted
from constant comprehensive treatment and less human disturbance. |
