中文摘要	从石漠化演化趋势、石漠化类型空间组合特征及景观格局方面分析了19902010年贵州六枝喀斯特区石漠化景观格局的变化。研究结果表明:六枝特区近20年石漠化景观类型面积变化较大,其中无石漠化景观类型面积增加了73.16km~2,石漠化强度有所减弱;无石漠化和轻度石漠化景观比例增加,无石漠化、潜在石漠化及轻度石漠化景观类型的斑块密度增高,同时轻度石漠化景观形状指数上升了4.57,斑块形状进一步复杂和不规则;研究区石漠化景观多样化指数(GM_k)较高,1990、2000及2010年平均值都在0.66以上,石漠化景观类型丰富,但景观破碎化度较大并有增加趋势。通过景观分析可以看出,近20年来研究区石漠化景观得到了恢复,低等级石漠化斑块增多,降低了原有高等级石漠化斑块的优势度。但是新恢复的低等级石漠化斑块没有连片形成优势,所以在今后的治理过程中应该人为加以引导,促使生态修复的斑块间打通廊道形成优势,形成稳定的生态系统。
英文摘要	This paper analyzed the landscape pattern change of karst rocky desertification from 1990to 2010in Liuzhi of Guizhou Province from the aspect of karst rocky desertification evolution trend,spatial combination characteristics and the landscape pattern. The results showed that:the area of karst rocky desertification landscape type of Liuzhi changed greatly in resent twenty years:the area of non-karst rocky desertification increased by 73.16km~2 and the strength decreased;the percentage of non and light Karst rocky desertification increased,the patch density of non,potential and light rocky desertification landscape type ascended.Meanwhile, the landscape shape index of light rocky desertification increased by 4.57and the shape of patches became more complicated and irregular.The rocky desertification landscape diversity index was higher and the average value of 1990,2000and 2010was greater than 0.66.The rocky desertification landscape type was various.However,the landscape fragmentation was higher with an ascending trend.From the aspect of landscape analysis,the rocky desertification landscape of the study area had recovered to some extent in the past twenty years;the patches of low grade rocky desertification ascended and the dominance of original high grade had been decreased.However,the newly recovered low grade rocky desertification was not contiguous;we should take some measures to make ecology recover patches be contiguous to form a stable ecosystem in the future management process.
