黄土高原耕地坡度分级数据集

数据来源：中国科学院地理科学与资源研究所（一）目的与意义土地利用不合理是导致黄土高原水土流失强烈的重要人为因素，土地利用不合理的集中表现是坡耕地面积大。根据我们的耕地坡度分级数据，黄土高原耕地面积为19425.92万亩，其中坡耕地（〉3°）为9269.64万亩，占耕地总面积的47.7%。在坡耕地中，〉7°的为7525.06万亩，占坡耕地总面积的81.2%；〉15。的为4178.47万亩，占44.8%；〉25。的为1106.43万亩，占11.9%。在黄土高原主体部分陕、晋、甘地区坡耕地中，〉7°的占80.7%；〉15。的占45.9%；〉25。占12.6%，可见，坡耕地是土壤侵蚀的重点。水土流失使坡耕地成为跑水、跑土、跑肥的“三跑田”，据资料，在7°以下的坡耕地，每年每亩流失土壤1t左右；25。左右的坡耕地，每年每亩流失土壤8-10t，致使土地日益贫脊，并加剧了干旱发展，导致农业生产低而不稳。在影响坡耕地土壤侵蚀强度的诸多因素中，地面坡度是最基本的因素。尽管坡度与侵蚀的关系很复杂，但一般情况下，土壤侵蚀与坡度成正比。即当径流相同时，坡度越大，侵蚀量越大；在同样的降水条件下，径流量随坡度增大而增加，水流的冲刷力加强，侵蚀量也随坡度增大而增加，这是黄土高原坡度影响侵蚀的基本规律。编制黄土高原地区抽样地段1：50000耕地坡度分级图并采用数学统计方法编制耕地坡度分级数据，是对黄土高原土地资源类型、数量、质量、分布等研究的深化和发展。其目的在于揭示坡耕地形成过程及坡度特征，以便进一步了解坡耕地水土流失规律，更好地为水土保持工作、土地资源的合理开发利用、农业生产的发展及黄土高原的综合治理开发提供科学依据。该项工作自1987年4月开始，至1990年9月结束。（二）方法方法有两种：通过编制黄土高原地区抽样地段1：50000耕地坡度分级图，并采用数学方法编制耕地坡度分级清单。（1）抽样地段的选择抽样地段是指在黄土高原地区耕地类型组合具有代表性，又有1：50000土地利用现状图或有航片、卫片可以编制1：50000耕地分布图的地段。选取典型地段面积最小为10cmX10cm，制图精度应满足抽样调查的要求。（2）耕地坡度分级指标代号12345T坡度<3°3°—7°7°—15°15°-25°>25°梯田（3）作法将收集到的或编制的1：50000土地利用现状图上的耕地和水平梯田解译在塑料薄膜上，然后将其套合在1：50000的地形图上，对所作的耕地坡度分级，即成耕地坡度分级图。（4）量算面积首先对耕地坡度分级图上的水平梯田和各坡度级的耕地进行面积量算。面积量算方法，各地有异：宁夏采用ML—II型面积扫描仪进行，甘肃采用求积仪法，陕西采用称重法，内蒙古则采用数方格法。要求每个图斑至少量算二次，在误差小于2%的情况下取平均值。在采用称重法时，称重系数、校核系数的计算公式：称重系数=样图总面积（亩）/样图称重（g）校核系数=（样图总面积一样图量算面积）/样图量算面积求出抽样地段耕地总面积。求出耕地坡度分级图所代表的区域面积。将若干抽样地段耕地坡度分级图上得到的各坡度级的耕地面积对应相加，并用对应抽样地段耕地面积之和相除，即得到各坡度级的耕地占抽样调查地段耕地面积的平均百分数。最后，根据抽样调查区域内的土地特征，综合分析并依据统计原理进行统计处理，汇总计算得到全县（市、旗）的各坡度级的耕地数量。利用土地概查、详查、土壤普查及农业区划的有关资料对所求得的面积（毛面积）再进行净耕地面积的校核。即分别扣除所包含的非耕地（小片林，草地，居民点，交通干线等）。对最终求得的耕地坡度分级面积按省（区）等进行汇总整理成数据。应当着重说明的是：由于受经费限制和1：50000土地利用现状图又极难收集得到，各地1：50000耕地坡度分级图的编制并未强求在资料、方法等方面完全一致，但主要工作步骤、程度及精度上是很接近的。由于受资料限制，有些地区梯田面积难以用抽样法弄清。最后梯田全部采用了1986年的统计面积。这里的梯田面积实际为梯、条田面积之和。还是由于上述原因，青海省与河南省分没有最终完成。在引用本数据集数据时务请注意数据所含范围。采用公里网点为抽样点，进行抽样调查。只有山西省采用了这种方法。其与第一种作法的最大区别是没有制图过程。山西省的耕地坡度分级数据是根据数理统计原理，通过抽样调查、定点实测、现场填写汇总计算而获得的。具体作法如下：（1）以1：50000地形图上平面直角坐标系单公里网点为抽样点，进行抽样调查。（2）结合土地利用现状调查，用森林罗盘实测全省156000个样点的位置。以样点为单位，按土地和现状分类标准，核实耕地，用仪器测定耕地实际田面坡度，就地填写在统一的调查表中。将田面坡度划分为＜3°、3°—7°、7°—15°、15°—25°、〉25°，并列出水平梯田，分别进行归类统计。统计全县的样点数，按抽样调查公式，计算全县耕地各坡度级的面积，最后逐级汇总，得到全省的耕地不同坡度的数据。分区说明综合治理开发分区为了因地制宜的对黄土高原地区实施综合治理开发，特将本区划分为在综合治理特点和经济开发方向上皆较一致的区域，即综合治理开发区。分区总的标准是突出环境治理与经济开发的关联性和整体性，并使区内在自然、经济、社会因素等方面具有最大的相似性。为了便于应用社会、经济统计资料和方便地方行政领导，分区保持县(市、旗)界的完整。土地潜力分区土地潜力区反映黄土高原地区范围内，区域间土地生产力的对比。在同一潜力区内，应具有大致相同的土地生产能力，包括适宜的作物、牧草和林木的种类、组成、耕作制度和产量水平，以及相似的土地利用方向和改良途径与措施。划分潜力区的依据是水热条件，其具体指标见《黄土高原地区土地潜力分区图》。出于上述同样原因，潜力区也保持县(市、旗)界的完整。土地利用分区土地的农业开发和利用具有明显的地域性和综合性。为了比较全面、系统地揭示和阐明土地资源特点及合理利用方向与途径，特划分土地利用区。土地利用分区的原则是：自然条件、土地资源特点及农业生产类型的相似性；土地限制因素及其开发利用方向、综合治理途径的相似性；出于上述同样原因，土地利用分区保持县(市、旗)的完整。第一部分：中国黄土高原地区耕地坡度分级数据各省(区)耕地坡度分级数据(万亩)省区土地总面积耕地总面积梯、条田耕地坡度分级地面坡度分级V3°3-7°7-15°15-25°>25°<3°3-7°7-15°15-25°>25°甘肃省16449.764979.031426.741176.71263.99909.05892.22310.323047.03740.713987.514976.173698.34山西省23469.717849.871408.153161.421124.991030.00907.18218.136127.522372.144815.944621.304532.82内蒙古自治区18489.102054.7032.941660.65283.5676.860.690.0014912.621405.271115.50647.49408.22宁夏回族自治区7778.541984.9073.51961.40261.38453.74218.7216.153806.21841.571339.731240.03551.00青海省5162.29803.5286.77一一一一一933.57117.891097.491532.791480.55陕西省19456.506637.36965.882458.84326.771140.701156.55588.625927.22624.012333.495361.455210.33河南省2760.671059.69276.48一一一一一895.21233.57470.78633.50527.61各综合治理开发区耕地坡度分级数据(万亩)区省区土地总面积耕地总面积梯、条田耕地坡度分级地面坡度分级<3°3-7°7-15°15-25°>25°<3°3-7°7-15°15-25°>25°河南省2760.671055.69276.48一一一一一895.21233.57470.78633.50527.61豫西晋东南区山西省5967.101512.81441.81508.40254.80182.66108.5316.811180.45626.031607.591519.721033.31晋北区晋北区6573.372278.09250.851035.78441.36296.99210.0843.032011.12891.141380.38922.351368.38汾渭谷地区山西省6801.512772.87498.951516.85275.71236.35204.3140.702590.35594.431190.071600.42826.24陕西省6697.683131.14432.971929.30164.17188.43298.40117.873051.64303.10484.761523.211334.97山西省1076.93山西省1076.93372.6144.1528.9324.58119.70123.9331.3266.4666.07279.14589.3975.87山西省1076.93山西省1076.93372.6144.1528.9324.58119.70123.9331.3266.4666.07279.14589.3975.87晋陕蒙接壤区陕西省内蒙古自治区2646.744013.60408.76545.7738.3813.4199.08268.4115.71192.80149.5770.4689.140.6916.880.001310.882199.3044.38846.37492.22758.22728.68201.8770.587.84晋西陕北区山西省陕西省3050.817265.20913.49172.5971.46128.54194.30260.3386.27279.15194.47358.76989.421229.012562.44318.22288.67116.45716.93694.27427.901119.99201.401046.592109.572787.65陇东陕北区甘肃省陕西省5188.372846.881327.74459.60407.5454.49135.07162.33108.711062.78115.38656.831879.331474.05535.02176.31141.7930.4485.7774.7425.97444.7175.13309.92999.991017.13两西天水区宁夏回族自治区甘肃省2521.605504.771035.122317.4265.80681.90253.08341.09117.77376.36206.8515.26382.85228.15793.89804.85311.8698.72525.61533.89136.21704.79201.041916.401711.37971.17鄂尔多斯区9418.34123.991.45122.540.000.000.000.009083.64292.7127.009.235.76内蒙古河套区5057.161384.9418.081269.7090.766.400.000.003629.68266.19330.28436.39394.62宁夏平原区5256.94949.787.71708.32143.6177.3811.870.893423.37613.42545.84435.18239.14兰州区5756.621333.87285.24428.08110.78248.37196.0065.401279.46424.291414.281385.471253.12青东高原区5162.29803.5286.77933.57117.891097.491532.791480.55各土地潜力区耕地坡度分级数据（万亩）区省区土地总面积耕地总面积梯、条田耕地坡度分级地面坡度分级V3。
