The conclusions show that most of the agricultural land resources are of good quality. However, the dry land and paddy field covering an area of \{17.11\} km\+2 are contaminated seriously heavy metals, which are not fit for growing crops. At the same time, the high\|quality plowland, which i...

定量评价的结果表明，区域农业土地资源中大部分土地资源质量较好，但旱地和水田共有 1 7.1 1km2 的重金属重度污染区，这部分耕地已不适宜种植农作物，同时，适合人类耕作的高质量耕地由于土壤重金属污染减少了近 1 / 3 ，说明贵阳市区进行土壤重金属污染防治具有重要的意义。

Then different runoff models and confluence processing patterns were adopted according to different characteristics of confluence inside and outside of polder s.

针对平原区下垫面多样变化和在分区内分布不均匀的特点，将平原区分解为水面、水田、旱地与城镇建设用地4种下垫面，分别采用不同的产流模型，根据圩区内外不同的汇流特性，分别采用不同的汇流处理模式。

This paper aims to find out the nutrition characteristics and fertilizer absorption rule of Castor in arid red soil districts under the subtropical climate of Yunnan province, and establish a corresponding fertilizing technology under the condition. It choose the variety TCO-202 of Castor (Ricinus communis L.) as test material to observe and record the dry matter accumulation of each organ as root, stem, foliage and inflorescence, which are in the five critical growth stages as seedling stage、 bud stage、 blooming stage、 filling stage、 maturation stage of Castor {Ricinus communis L. respectively, and measure out the fertilizer absorption amount of nitrogen, phosphorus and potassium.

本文以云南北亚热带气候下的红壤旱地为试验条件，选用蓖麻品种TCO-202为试验材料，通过对苗期、现蕾期、开花期、灌浆期、成熟期五个蓖麻生长关键时期根、茎、叶、花序各器官的干物质积累和氮、磷、钾吸肥量的测定，研究云南红壤上蓖麻的营养特性和吸肥规律；依据蓖麻的营养特性和吸肥规律，结合云南红壤氮、磷、钾的含量与利用效率，制定适合云南红壤上蓖麻栽培的施肥技术研究方案。

The results showed that "Green Drought Resistance agent NO.1, NO.2 and NO.3" harmonized ear number, spike number and 1000-seed weight of winter wheat in dry land, they have good yield-improving effects. The drought-enduring experimentation showed that with the raising of the PEG density, the restrain that burgeon and rootage got on each treatment were more obvious. The drought resist of burgeon ratio, length of bud, rootage ratio, number of root and length of root treated by GDR1 was better than check's.

结果表明：GDR1号、GDR2号和GDR3号抗旱剂较好地协调了旱地冬小麦的穗数、穗粒数、千粒重，具有较好的产量效应；耐旱性试验表明，随着PEG浓度的增高，各处理发芽和生根受到抑制作用越明显，GDR1号处理的发芽率、芽长、生根率、根数和根长的抗旱性优于对照；不同土壤水分条件下绿色抗旱剂GDR1号的出苗率、幼苗和根系生长与不同PEG浓度条件下的处理结果相一致。

The results showed that the areas of land for building, water area and fishery land increased. Paddy field, dry agricultural land, tidal flat, forest land and saltern decreased.

结果表明，杭州湾南岸滨海平原建设用地、水体和养殖用地呈现明显的增长趋势，水田、旱地、滩地、林地和盐田呈减少趋势。
