Xishuangbanna Dai Autonomous Prefecture (XSBN) lies in the core area of the “One Belt and One Road” policy, and its strategic location has constantly drawn attention. Driven by market demand and the economy, rubber planting areas have been transplanted from traditional growing areas to and is now cultivated in almost all tropical zones (Malaysia, Laos, Myanmar, Thailand, Vietnam, Cambodia, etc.) in the past 20 years, with a transplanting area over 1 million square hectares. As of June 2022, the Association of Natural Rubber Producing Countries (ANRPC) reported that the global natural rubber production is 1.113 million tons, with an increase of 3.8% over the same period in 2021, while global consumption is expected to grow at a faster pace of 5.8% over the same period, to 1.206 million tons. With the increasing demand for rubber in national defense and latex production, the planting area of artificial rubber plantations has shown a trend of substantial growth and continuous expansion in tropical rainforest areas worldwide. As the only renewable green energy material among the four major industrial raw materials, rubber is known for its economic values and carbon sequestration potential. Rubber, a tropical evergreen broad-leaved vegetation, originates from the Amazon basin forest of South America. The method proposed provides reliable results on spatial distribution of rubber, and is potentially transferable to other mountainous areas as a robust approach for rapid monitoring of rubber plantations. The OA value and Kappa coefficient were stable in the range of 0.88–0.90 and 0.84–0.86, respectively. The results show that: (1) the identification results are in consistent with field survey and rubber plantations area generally shows a first increasing and then decreasing trend (2) the Overall Accuracy (OA) and Kappa coefficient of the proposed method are 90.0% and 0.86, respectively, with a Producer’s Accuracy (PA) and User’s Accuracy (UA) of 95.2% and 88.8%, respectively (3) cross-validation was employed to analyze the accuracy evaluation indexes of the identification results: both PA and UA of the rubber plantations stay stable over 85%, with the minimum fluctuation and best stability of UA value. Five classification schemes were constructed for comparison, and the one with the highest classification accuracy was used to identify the spatial pattern of rubber plantations in 2014, 2016, 20 in Xishuangbanna. On the basis of optimization of input samples and features, phenological spectrum, brightness, greenness, wetness, fractional vegetation cover, topography and other features of rubber were extracted. In this paper, we proposed a classification method combines multi-source phenology characteristics and random forest algorithm. However, the spectral characteristics of rubber tree is easily mixed with other vegetation such as natural forests, tea plantations, orchards and shrubs, which brings difficulty and uncertainty to regional scale identification. Therefore, understanding the spatial distribution of rubber plantations is crucial to regional ecological security and a sustainable economy.
