尽管人口减少，但由于定居，对空间的需求仍然惊人。因此，根据德国环境指数（Deutscher Umweltindex DUX）的环境晴雨表，不断增长的居住量和交通量是德国最紧迫的环境问题。我们距离实现到 2020 年将土壤需求量从目前的 119 公顷/天减少到 30 公顷/天的既定目标还很遥远。2003 年，德国的定居面积增长了 1.0%，交通面积增长了 0.4%（总计 341 平方公里，占德国总面积的 0.8%）（德国联邦统计局，2004 年）。自第一次全德国土壤抬高以来，参考1993年的实际使用，定居面积和交通面积增长了11.9%！平均约 50% 的定居点区域是建成区或封闭区；就交通区域而言，土壤封闭率要高得多（环境局，2003 年）。
Despite of a decreasing population there is still an alarming demand for space because of settlement. Therefore the growing volume of settlement and traffic is the most urgent environmental problem of Germany according to the environmental barometer within the German Environment Index (Deutscher Umweltindex DUX). We are far away from reaching the set goal of reducing the demand for soil from momentarily 119 ha/d to 30 ha/d till 2020. In 2003 the settlement area in Germany grew by 1.0 % and the traffic area by 0.4 % (altogether 341 km2 or 0.8 % of Germany’s total area) (Federal Statistical Office Germany, 2004). Since the first all-German soil elevation, in reference to the actual use in 1993, the settlement area and the traffic area grew by 11,9 %! In average approximately 50 % of the settlement area is a built-up or sealed area; regarding the traffic area the soil sealing rate is considerably higher (Environmental Authority, 2003).
