- 摘要:
- 西南地区石漠化问题是我国土地退化的三大问题之一，也是学界长期以来关注的问题。利用Landsat数据提取了贵州省铜仁地区2000-2014年的石漠化情况，并对其演化过程中的时空特征进行了分析，进而利用空间面板数据回归对其经济驱动力进行了研究。结果显示：（1）铜仁市石漠化情况主要出现在西北部，其集聚态势十分显著；（2）空间转移概率矩阵显示石漠化整体改善的趋势比较明显，但潜在石漠化地区的控制并不容易，因此应着眼于潜在石漠化地区的控制的改善，防微杜渐，从源头上遏制恶化的趋势；（3）种植业对于石漠化有抑制作用，而畜牧业的发展则加剧了石漠化的恶化，而工业与服务业则有助于控制石漠化的扩张。最后，提出了重点治理、全面控制、加速推进现代化农牧业和旅游业发展3条发展建议。
- Abstract:
- The rocky-desertification in Southwest China is one of the three major problems of land degradation in China, and was concerned by researchers. This study was based on Landsat data and extracted rocky-desertification information during 2000-2014, analyzed the spatiotemporal characteristics of evolutionary process, and then used spatial panel data regression to examine the economic driving forces of this phenomenon. The results show that:(1) rocky-desertification mainly occurred in the northwest of Tongren, and agglomeration was remarkable; (2) the matrix of space-time transfer probability demonstrates that ameliorate of rocky-desertification is obvious, but control of the potential rocky-desertification is not easy, it should be the core of control measures; (3) farm is the inhibited factor of rocky-desertification and graziery drives therocky-desertification, the industry and services would help to retard the expansion of rocky-desertification. According to the conclusions, it is suggested that administer of key region, monitoring of potential region of rocky-desertification, and boosting the modern husbandry and tourism would be the keys to local rocky-desertification control.
