Novel cropping system strategies in China can increase plant protein with higher economic value but lower greenhouse gas emissions and water use

This database contains the average crop residue, manure nitrogen, manure organic carbon, net greenhouse gas emissions, and cropland area for 17 cropping systems at prefecture level during the period 2014-2018. In addition, it contained the changes of net greenhouse gas emissions caused by the optimization at prefecture level and province level. We also shared the key code for optimizing cropping systems at prefecture level and provided the all data. Users can run it the Matlab platform.本数据库收录了2014-2018年期间，17种种植制度在地级市（prefecture level）尺度下的平均作物残茬、粪肥氮、粪肥有机碳、温室气体净排放量及农田面积数据。此外，本数据库还包含地级市与省级尺度下，种植制度优化所带来的温室气体净排放量变化量。本次研究同步共享了地级市尺度下种植制度优化的核心代码，并提供了全部数据集。用户可在Matlab平台上运行该代码。
