新西兰 60% 的高度侵蚀土地位于北岛，严重侵蚀影响着土地生产力、水质和基础设施。 60% of New Zealand's highly erodible land is in the North Island, with high erosion impacting land productivity, water quality, and infrastructure.
根据新西兰统计局的数据，新西兰 60% 的高度侵蚀土地位于北岛，尽管其面积仅占全国土地总面积的 43%。 60% of New Zealand's highly erodible land is located in the North Island, despite covering only 43% of the nation's total land area, according to Stats NZ. 陡峭的地形、高降雨量和地震导致严重的水土流失，从而影响土地生产力、水质、自然景观和基础设施。 The steep terrain, high rainfall, and earthquakes contribute to high levels of soil erosion, which can impact land productivity, water quality, the natural landscape, and infrastructure. 2022 年，估计有 1.82 亿吨土壤侵蚀进入新西兰河流。 In 2022, an estimated 182 million tonnes of soil erosion entered New Zealand's rivers.
