| 人为干扰已经成为影响自然保护区自然生态系统的最主要的干扰因素之一。在广东云开山国
家级自然保护区选取数量多、影响范围广的受种植、道路、风电以及坟墓等 4 个干扰类型的土壤为研究
对象，研究人为干扰下土壤环境的变化，测定其土壤理化性质特征。结果表明：土壤毛管持水量和毛管
持水率呈正相关性，坟墓干扰下样地的毛管持水性最好；土壤总孔隙度变动与土壤容重变动呈现反比例
关系。坟墓干扰下的环境土壤稀松、结构性较好，风电干扰下的环境土壤结构性较差，土壤持水性表现
较差。全氮和碱解氮这两个指标呈现出一致的趋势，两者总体表现为对照点＞干扰点，其中坟墓干扰＞
种植干扰＞风电干扰＞道路干扰。有效磷与全磷指标表现出正相关规律，但规律不显著，其中对照点＞
干扰点。 |

| Abstract: |
| Human disturbance has become one of the most important factors affecting the natural ecosystem
of nature reserves. In this study, a large number of soils disturbed by planting, road, wind power, and tomb
interference were selected in Guangdong Yunkaishan National Nature Reserve as the research objects. In order
to study the changes of soil environment under human disturbance, the soil physiochemical properties were
determined. The results showed that: there was a significant positive correlation between soil capillary water
holding capacity and capillary water holding rate, and the capillary water holding capacity of the sample plot of
tomb disturbance was the best. The change in soil total porosity was inversely proportional to the change in soil
bulk density. The environmental soil under the interference of tombs was loose and structurally good, while the
environmental soil under the interference of wind power was structurally poor and the soil water holding capacity
was poor. The two indicators of total nitrogen and alkali-hydrolyzable nitrogen showed a consistent trend. The
overall performance of the two was control point > interference point, in which grave interference > planting
interference > wind power interference > road interference. Available phosphorus and total phosphorus index showed a certain degree of positive correlation, but the variation was not obvious, the control point > interference
point.
