A field experiment was undertaken to identify profitable land use based on productivity, net present value, biomass and carbon stocks in litchi based land uses (LBLUs) during 1995–2015 established on degraded riverbed lands of western Himalaya, India. Results of LBLUs (20 years) revealed that LCT + LH + LPG land use produced 6.10–25.27%, 5.82–14.92% and 3.45–13.62% more fruit yield, 14.61–25.22%, 10.18–16.38% and 9.10–16.62% more total biomass, 2.95–9.51%, 0.03–4.54% and 1.60–8.26% higher carbon in soil and 6.93–14.76%, 4.60–10.03% and 6.29–13.14% more total carbon stocks as compared to sole litchi land use of 1st, 2nd and 3rd phase, respectively. Similarly, 80.39% and 78.56% more NPV, 11.74% and 19.77% higher BCR with shortest payback period (5 years) were realized in LCT + LH + LPG land use for 20 and 50 years, respectively. Sensitivity analysis also revealed that changes in discount rate will not affect its performance ranking.

印度喜马拉雅西北部退化土地在雨养条件下基于荔枝 (Litchi chinensis Sonn.) 的农业园艺土地利用的表现

1995 年至 2015 年期间，在印度喜马拉雅西部退化河床土地上建立的荔枝土地利用 (LBLU) 中，根据生产力、净现值、生物量和碳储量进行了实地试验，以确定有利可图的土地利用。LBLUs（20 年）的结果显示，LCT + LH + LPG 土地利用产生了 6.10–25.27%、5.82–14.92% 和 3.45–13.62% 的水果产量，14.61–25.22%、10.18–16.38% 和 16.12% 和 16.9.9.总生物量，土壤中的碳高 2.95–9.51%、0.03–4.54% 和 1.60–8.26%，与唯一荔枝土地利用相比，总碳储量高 6.93–14.76%、4.60–10.03% 和 6.29–13.14%分别是二期和三期。同样，LCT + LH + LPG 土地使用分别为 20 年和 50 年，分别实现了 80.39% 和 78.56% 的 NPV、11.74% 和 19.77% 的 BCR，以及最短的投资回收期（5 年）。
