The Spatial Analysis of Betel Nut Plantation Hot Spots in the Upper Shui-Li Creek Watershed [PDF]
, 2014 This study investigated the spatial distribution of BNP hot spots in the upper Shui-Li Creek watershed. Two spatial autocorrelation methods, Moran’s I and G statistics, were selected for analyzing the spatial cluster of BNPs with different grid sizes ...

Shuitu Baochi Xuebao, 2018 受地质背景的强烈制约，西南喀斯特地区土壤侵蚀与其他类型区显著不同，叠加了化学溶蚀、重力侵蚀和流水侵蚀的耦合作用，呈现地面流失和地下漏失的混合侵蚀机制。从土壤地表侵蚀产沙、土壤地下漏失、土壤侵蚀强度与分级标准、土壤侵蚀过程模拟等几个方面简要综述了该区土壤侵蚀特征，并对未来研究方向进行了展望。今后应该加强西南喀斯特地区水土流失途径与土壤流失/漏失定位监测技术研究，进一步发展水土二元流失模拟模型，为该区土地利用变化的水土保持功能定量评估提供科技支撑，服务石漠化综合治理和后续规划制订。

Shuitu Baochi Xuebao, 2002 水土流失是自然过程与人为活动叠加的结果,它既可成为祸害的源头,也可构成水土资源转移的方式.就其危害的方面来说,显然应予控制,但从其资源的性质来看,又应加以利用.尤其不可在消除一种生态损害时又在制造另一种新的生态损害.这就决定了对水土流失应实施适度治理.长江流域水土流失适度治理中"适度"的基本标准是冲淤平衡,即着重考虑河道、河口三角洲及海岸线的稳定,且兼顾全流域的利益,将水土流失控制在一个适宜的范围,并采用"补偿"的办法减轻流失区因此继续承受的损失.具体操作中宜实施总量控制,以达到"适度 ...

Shuitu Baochi Xuebao, 2007 花岗岩母质土壤区在洞庭湖流域广泛分布,由于内在机理及洞庭湖流域特殊的气候条件和人地关系状况,使这一类土壤区成为洞庭湖流域最为严重的水土流失地区之一,产生严重的环境、社会、经济后果.花岗岩分布区地形陡峭,风化速度快,风化层深厚,极易导致水土流失.在内生动力和外部动力的共同作用下,水土流失的时序特征与风化层各层的特性紧密相关.为了科学治理,首次尝试对湿润区花岗岩水土流失区进行区域界定并作了类噜型区划分.在防治方面提出树立全新的农林发展观,以流域经济区为单位进行用地结构调整,同时提高治理水土流失的科学性 ...
