内容記述 黄土丘陵ガリ区は中国における侵食の激しい地域の一つである。激しい土壌侵食に半乾燥・乾燥気候,峻険な地形と悪化した生態環境に加えて,土地生産力は極めて低く,住民の生活も貧困である。このような自然・経済状況に鑑み適当な侵食防止策と農業開発技術を探討する為に,「黄土丘陵ガリ区における小流域の土壌侵食防止と農業開発技術に関する研究」を国家の指定研究課題とし,北京林業大学が寧夏回族自治区の西吉県の黄家二岔小流域において,1981年から一連の研究を行ってきた。採用された技術は該当地域の資源レベルと一致し,研究成果は類似な小流域にも適用・普及できる。黄家二岔小流域の侵食防止・農業開発の実際により,流域管理事業には連続的な資金・技術投入があれば,土砂流失は98%まで低減でき,食糧生産高と住民の年平均収入がそれぞれ526%と566%まで増加できるとされている。本研究は当該小流域の侵食防止措置と侵食防止事業の効果について検討するものである。
